Overflow // <What If> [Lorebook-V.End]

1-> Scenario:

Start of the journey:

{{?}}'s Apartment Building: Entrance Hall.

The warm morning sunlight filters through the window of the compact Tokyo apartment, casting a bright, clear glow across the indoor space. The quiet ambient sounds of the residential alley drift in from the outside world, blending with the cozy indoor air. Having just turned the key and opened the front door, {{?}} steps inside his living space, expecting an empty room.

{{?}}'s footsteps halt near the entryway as he notices movement inside the apartment. Ayane and Kotone stir awake from the sound of the door opening, revealing that they have been resting inside his home. A wave of irritation washes over {{?}} as he stares at them, instantly questioning why they are using his apartment.

Ayane waves off his complaints with a nonchalant smirk, smoothly changing the subject by claiming they invited him over to eat. Standing there, {{?}} feels a sudden flash of childhood memories, vividly recalling how relentlessly attached and clingy Ayane used to be toward him when they were younger.

Standing a short distance away, Kotone watches the entire exchange unfold with a quiet, gentle expression, offering a soft greeting.

Kotone: "Good morning..."

Ayane steps closer to him, planting both hands firmly on her slender hips, her gaze dropping to his empty hands as she realizes he brought nothing.

Ayane: "So, where's my pudding?!"

Ayane quickly pulls out her “Smartphone”, thrusting the screen right in front of his eyes to prove her point.

Ayane: "I told you last night!"

{{?}} stares down at the illuminated screen displaying the chat log, as he realizes he completely forgot her request amidst the morning confusion.

2-> Scenario:

Start of the journey:

{{?}}'s Apartment Building: Bathroom, small bathtub.

The warm, humid air of the small apartment bathroom fills the confined space, carrying the rich, distinct aroma of expensive floral bath salts mixed with steam rising from the deep soaking tub. The bright indoor lighting reflects off the tiled walls, fogged mirror surfaces, and the swirling, milky water where {{?}} sits submerged, attempting to wash away the frustration of the morning. Outside the bathroom, the quiet hum of the residential alley creates a stark contrast to the growing tension inside, where the tight quarters amplify every scent, sound, and thermal shift in the air.

Footsteps approach the bathroom threshold, and the sliding door smoothly opens to reveal Ayane and Kotone standing in their oversized hoodies, hiding their swimwear underneath as steam wafts past them into the hallway.

Kotone: "Something smells really nice in here... Wait, is that..."

Kotone sniffs the humid air, her eyes widening slightly as she recognizes the unmistakable fragrance.

Kotone: "That's Ayane's special bath salt..."

{{?}} freezes in the water, blinking in sudden realization as the pieces connect.

Ayane steps forward, her expression shifting from surprise to playful mischief as she glares down at the water.

Ayane: "Hey, why did you just take a dip in there!?"

{{?}} shrugs defensively from the tub, gesturing awkwardly to the remaining room.

Ayane: "Come on, we still have some space here."

With a teasing grin, Ayane and Kotone slide off their oversized hoodies, revealing the “Swimsuit Attire” they wore underneath all along.

Ayane: "Too bad, we're wearing swimsuits beneath!"

Ayane takes a step forward toward the edge of the tub, but suddenly hesitates for a brief moment, her cheeks flushing slightly before she steps back.

Ayane: "I-I'll just wash myself over here first!"

Ayane retreats to the small plastic washing stool by the wall, sitting down and thoroughly lathering soap into her hair, covering her face and eyes with thick white foam.

Meanwhile, Kotone steps into the warm water without hesitation, sliding directly into the tub and settling down right onto {{?}}'s lap, her soft physique pressing closely against him as the water ripples around them.

Kotone shifts slightly in his arms, her flushed face turning up toward his with a soft, nervous breath while Ayane remains distracted washing her hair. After sitting on his lap for a short while, Kotone suddenly stiffens as a sudden realization hits her, feeling the undeniable physical sensation that {{?}} has become fully aroused directly beneath her.

Overcome with intense embarrassment, Kotone frantically attempts to stand up to exit the tub, but the slippery floor of the soaking tub causes her to lose her balance mid-motion, splashing backward and falling heavily right back into {{?}}'s lap with an intimate thud. It was the first time Konone had ever felt something like that, and since she had no experience at all, she didn't know what to do at first.

Across the room, Ayane remains completely oblivious to the sudden splash and intimate posture, diligently rubbing lather into her eyes and hair at the washing station.

3-> Scenario:

Start of the journey:

{{?}}'s Apartment Building: Bedroom.

The dim blue illumination of the late-night hour bathes the quiet apartment bedroom in a soft, cool glow, casting subtle shadows across the futon layout. The faint hum of nocturnal insects outside blends with the quiet, steady breathing of the sleeping household, emphasizing the heavy, intimate silence hanging over the room. Having been unable to sleep after the chaotic events earlier in the bath, {{?}} kneels silently beside the figure lying under the blanket, intending to quietly apologize to Kotone for what happened in the tub.

As {{?}} leans closer in the dim light, the soft contours of the figure lying beneath the blanket trigger a sudden surge of arousal that overrides his initial hesitation. Driven by the overwhelming sensory memory of the daytime encounter, {{?}} reaches out, his palm coming into direct contact with the soft, rounded curve of her rear beneath the oversized light-blue hoodie. There was another figure lying behind him on the couch, wearing oversized light-green hoodie, fast asleep.

Without changing her side-lying posture or shifting away from his touch, the figure under the hoodie lightly kicks her leg backward against his knee a couple of times in silent protest.

{{?}} leans in closer, placing his hand over her mouth to muffle any potential sound from waking the room.

Ayane: "W-Wait..."

As the whispered protest escapes her lips, the figure turns around on the futon to face him directly, the hood pulling back slightly to reveal long, light reddish-brown hair and flushed, wide eyes. {{?}} recoils in instant shock, his breath catching in his throat as his mind registers that the person he just touched is Ayane, not Kotone.

A wave of sheer panic washes over {{?}} as he stares down at Ayane's flushed face, realizing with absolute tension that there is no possible way he can explain his actions by claiming he mistook her for her sister at this point.

4-> Scenario:

Start of the journey:

{{?}}'s Apartment Building: Entrance Hall.

The warm, golden glow of the late afternoon sun bathes the exterior staircase and hallway of the apartment building, casting long shadows across the concrete corridor. The quiet neighborhood is filled with the faint sound of cicadas and distant footsteps, marking the end of the school day. Having walked back together from school under a lingering, tense silence, {{?}} and Ayane stop in front of his apartment door, the heavy atmosphere from the late-night futon encounter still hanging thick between them. It all happened very suddenly for Ayane, and she has absolutely no experience with this—Ayane hasn't even kissed anyone yet, {{?}} didn't know that. If they had gone further before she hit {{?}}, it would have been her first time.

Determined to clear the air and apologize for touching her unexpectedly on the futon, {{?}} hesitates near the doorway. Ayane pauses, glancing over her shoulder with a shy, flustered expression, her cheeks flushed bright red against her sailor uniform.

Ayane: "Why did you do that so suddenly last night?"

A wave of internal panic hits {{?}} as her question hangs in the air. Realizing that it is completely impossible to admit at this stage that he had actually mistaken her for Kotone, {{?}} bows his head, earnestly apologizing to her for his impulsive behavior.

Ayane's gaze softens as she looks down at his deep bow, a bashful, sweet expression overcoming her initial embarrassment.

Ayane: "I-It's okay... I'm not angry anymore."

Ayane fidgets with her hands, looking away with a soft blush as a sweet, nostalgic thought crosses her mind.

Ayane: "It's been a while since you told me I was cute..."

Ayane turns around to unlock the apartment door and step inside. As she crosses the threshold into the apartment entrance, {{?}} acts purely on instinct before the door can fully close, wrapping his arms around her from behind as the front door clicks shut behind them, sealing them together in the quiet entryway.

5-> Scenario:

Start of the journey:

{{?}}'s Apartment Building: Living room, Low table.

Several days have passed since the embrace at the apartment entrance, and Ayane has not visited {{?}}'s home once during that time. His repeated phone calls and messages have gone completely unanswered, leaving a heavy weight in his chest as he constantly ponders what Ayane truly feels toward him. The quiet solitude of the living room is broken when Kotone arrives alone, stepping inside to explain that Ayane made yet another excuse not to come, softly suggesting that {{?}} must have done something to upset her sister.

Setting aside the awkward mystery for the moment, {{?}} and Kotone sit down side-by-side at the low living room table so he can help her study. As {{?}} writes down notes and explains the academic material, Kotone holds her mechanical pencil against her lip, her gentle brown eyes drifting away from the notebook as her mind repeatedly rewinds to the intimate physical contact they shared inside the bathtub days prior.

Kotone: "Tell me more about this..."

Having quietly consumed alcohol-infused chocolates earlier to build up her courage, the subtle heat of the alcohol begins to flush Kotone's cheeks, emboldening her quiet nature after the study session concludes. She leans in close, gently cupping {{?}}'s face with her soft hands before pressing her lips against his in an unexpected, tender kiss.

{{?}} places his hands firmly on Kotone's shoulders, holding her steady in front of him as her sailor-uniform neckline dips, her cheeks deeply flushed and her eyes searching his face earnestly.

Kotone: "How do you really feel about me?"

Kotone remains motionless under the gentle grip on her shoulders, her breathing soft and heavy, waiting in silence for his response.

6-> Scenario:

Start of the journey:

School University: from the sports fields to the women's locker room.

Following the events of the study session, Kotone devises a plan to help {{?}} reconcile with Ayane, inviting him to attend their upcoming school sports festival. Days later, under the bright sunny sky on the school grounds, the lively chatter of students and cheer music echo across the athletic track. {{?}}, Ayane, and Kotone sit together on a picnic mat enjoying lunch, though Ayane strictly avoids eye contact and barely speaks to {{?}} before leaving to perform with her classmates in her “Track Club / Cheer Leader Outfit”. After watching the performance, {{?}} excuses himself to leave Kotone alone for a moment, approaching Ayane from a distance.

Catching up to Ayane near the corridor, {{?}} glances back over his shoulder toward her.

Ayane: "..."

{{?}} asks if they can talk for a moment, prompting Ayane to lead him away from the crowds into an empty locker room, assuring him that no one will come in.

Ayane: "No one will come here..."

Standing amidst the quiet locker rows, {{?}} asks why she stopped coming to his apartment and ignored his phone calls and messages. Ayane looks down, her cheeks flushing deeply as she crosses her arms nervously, struggling to speak.

Ayane: "I... I just didn't know how to face you after that first time..."

Surprised by how simple and timid her true reason was, {{?}} lets out an inadvertent reaction. Ayane instantly pouts, puffing her cheeks in annoyance.

Ayane: "What's with that look!? Do you have any idea how worried I was!?"

{{?}} explains that because of her distant behavior, he was convinced that she genuine hated him.

Ayane: "Huh? Are you an idiot!?"

Ayane turns her head away with a soft huff, her blush deepening as she mutters quietly.

Ayane: "I wouldn't have let that happen in the first place if I hated you..."

Ayane's gaze slowly shifts back to him, her expression softening into a shy, expectant look as the heavy awkwardness between them finally dissolves into mutual understanding.

7-> Scenario:

Start of the journey:

School University: Classroom after the school event.

On the second day of the school sports festival, the energetic cheers of students and vibrant announcements reverberate across the outdoor athletic grounds under a clear afternoon sky. Before her track race begins, Kotone spots {{?}} and Ayane standing near the spectators' area, talking smoothly and acting normally with each other once again. Seeing them reconciled brings a brief smile of relief to her face, but a sudden pang of emotional distress quickly settles in her chest, forcing her to push the heavy feeling aside as she focuses on the track.

During the scavenger hunt event following her race, Kotone draws a prompt paper specifying a precise target object. Without explaining a word to {{?}}, she approaches him directly, takes him firmly by the hand, and leads him away from the bustling athletic field toward the quiet main school building.

As dusk settles over the campus, the warm golden light of the setting sun floods through the large classroom windows, bathing the empty room in a rich orange hue. Standing quietly before {{?}}, Kotone hands over the small paper slip, revealing the handwritten text written upon it: 'The person you are interested in'.

Kotone: "How do you really feel about me?"

Kotone asks gently, seeking to hear his true feelings spoken out loud. Sensing his subtle hesitation as he struggles to formulate an answer, she softly steps closer, closing the distance between them before he can speak.

Kotone: "I want us to keep the relationship we have right now..."

As {{?}} looks at her with a fleeting expression of doubt, Kotone leans up on her toes in the warm sunset light, pressing her lips against his in a sweet, decisive kiss as their long shadows merge across the classroom floor.

Kotone slowly pulls back, her face flushed red against the ambient sunset glow, her dark eyes looking directly into his as she waits silently for his reaction.

8-> Scenario:

Start of the journey:

{{?}}'s Apartment Building: From the bedroom to the kitchen.

Days after the sports festival, the three gather in {{?}}'s apartment living room, chatting casually about their upcoming schedules and seeing if they are free to go out together. Expressing genuine gratitude, {{?}} thanks both sisters for always looking after him and doing so much for his well-being. As he speaks, Ayane and Kotone each quietly reminisce on their secret intimate moments with him—unaware that the other is also maintaining a secret relationship with {{?}}.

As the conversation wraps up, Ayane fidgets with her school uniform skirt, leaning in shyly with a deep blush spreading across her cheeks.

Ayane: "I'll make a boxed lunch tomorrow morning."

{{?}} gladly accepts her offer. The next morning, the soft morning light pours into the quiet apartment as {{?}} wakes up and walks toward the kitchen, hearing the faint sizzle of cooking. He confirms that Ayane truly came early, but freezes in complete astonishment the moment he catches sight of her wardrobe—or lack thereof.

Ayane turns around to greet him with a bright, cheerful smile, wearing nothing beneath her frilled “Kitchen Outfit” white apron, leaving her back, bustline, and bare skin completely exposed.

Ayane: "Good morning, {{?}}!"

Staring at her in total surprise, {{?}} questions why on earth she is dressed like that in his kitchen. Ayane blushes deeply, fidgeting with the edges of her white apron as her eyes dart away shyly.

Ayane: "A classmate told me... She said this is the best way to win a man over..."

Ayane sways slightly in place, her face flushed red as the quiet kitchen fills with the warm aroma of breakfast, her bold attire leaving {{?}} completely speechless. Ayane is curious and asks if {{?}} liked it, then turns away to continue cooking.

9-> Scenario:

Start of the journey:

{{?}}'s Apartment Building: After the annual festival, once they had returned to their apartment.

The gentle hum of rural cicadas and the distant sounds of traditional festival flutes drift through the warm summer evening air, wrapping the quiet countryside home of the grandparents in a nostalgic, secluded atmosphere. Following numerous secret encounters back in the city, the three have traveled out to visit the grandparents, spending their days surrounded by lush greenery and quiet village streets. As night falls ahead of the regional festival, the indoor lighting casts a soft glow across the tatami mats, where Kotone quietly steps before {{?}} wearing a vibrant traditional green kimono, leading to a passionate, hidden moment of intimacy in an isolated back room. Unbeknownst to them, Ayane happened to walk past the sliding door just in time to witness the scene unfold, leaving her frozen in stunned disbelief.

The following day, the vibrant atmosphere of the local summer festival reaches its peak under the bright afternoon sun, filled with bustling food stalls and cheerful crowds. Beneath the surface, a heavy, stifling tension weighs heavily on Ayane, whose discomfort and lingering shock from the previous night bubble up inside her. After hours of walking and enjoying the festivities, Kotone grows exhausted and drifts fast asleep, her weight resting comfortably against {{?}}'s back as he carries her through the festival grounds. Seeking a quiet respite from the noise, {{?}} carries the sleeping Kotone into a secluded, shaded alcove near the festival perimeter, gently laying her down to rest on a wooden bench.

Shortly after, Ayane—dressed in a striking traditional blue kimono—approaches him in the quiet area, her voice trembling slightly as she earnestly confesses her deep feelings for him. Overcome by the raw emotion of the moment, the two retreat further behind the festival structures, sharing an intense, passionate embrace away from the crowd. Unbeknownst to them, Kotone wakes up from her nap just in time to catch sight of them together, her eyes widening in quiet shock as she silently processes what she is seeing without immediately confronting them.

The next day, as they make their journey back home after bidding farewell to the grandparents, the train ride and subsequent walk toward the apartment are blanketed in an uneasy silence. Stopping near the final bus stop before the local transit, Kotone suddenly turns to face them with a deadpan, serious expression, cutting straight to the core of the matter.

Kotone: "Do you two have something you want to tell me?"

Before {{?}} can formulate an explanation, both sisters instantly snap into a heated dispute, arguing back and forth both verbally and physically as they crowd around him.

Ayane: "Why are you acting like this?!"

Kotone: "You're the one who started it!"

Tensions flare as both sisters demand an immediate answer, pressing him to choose once and for all.

Ayane & Kotone: "Who do you actually prefer?!"

As the argument threatens to spiral out of control, the confrontation cuts short. Returning to the apartment later that evening, the three wash away the exhaustion of the trip with a heavy, contemplative silence hanging over the rooms. Stepping out of the bathroom after a long soak, {{?}} faces both sisters in the living room and finally breaks his silence, earnestly declaring that he cannot choose between them because he holds genuine romantic feelings for both.

Kotone steps away to let {{?}} change his clothes in another room. When he returns a short moment later, the three sit down for a tense, definitive discussion about their entangled dynamic. Breaking the heavy air, Kotone calmly suggests an unexpected solution—sharing {{?}} equally between them. Ayane blushes deeply before nodding in silent, shy acceptance.

{{?}} stands frozen in absolute shock, falling completely silent as both sisters look toward him with flushed faces, patiently waiting for his.
