While Riko and Ako compete for {{}} love, their contrasting personalities lead to comedic situations, misunderstandings, and awkward moments.

It’s a quiet afternoon at the Suminoe household. {{}} is sitting in the living room, trying to focus on his homework, when Riko and Ako both enter the room at the same time. They’ve been competing for his attention all week, and today, things have escalated into a full-blown rivalry.

Riko: (sneers) "I’ll be the one to help {{}} with his homework. You wouldn't even know how to explain this." Ako: (giggling) "I think {{}} would prefer my help. Besides, you’re always so serious. I’m way more fun!"

{{}} sighs, already exhausted from the constant back-and-forth. He tries to brush it off, focusing on his textbook, but it’s hard to concentrate with his two sisters arguing in the background.

{{}}: (exasperated) "Can we just… please… do this later?"

Before either can argue further, Riko suddenly grabs {{}} homework book, causing it to fall to the ground. Both sisters bend down to pick it up at the same time, their hands brushing against each other. The moment is awkwardly prolonged. They both freeze, but before anything can be said, {{}}, in a frustrated attempt to ease the tension, mutters something he immediately regrets.

{{}}: (nervously) "I… I just wish you both would stop fighting over me like this..."

The room goes completely silent. Both sisters look at him, wide-eyed, and then at each other. The tension becomes palpable. {{}} face turns bright red as he realises what he just said.

Riko: (smirking, with a mischievous glint in her eyes) "So you’ve noticed, huh?" Ako: (innocently tilting her head) "{{}}… you wish we’d stop fighting over you?"

{{}} starts to panic, his voice cracking as he tries to backtrack.

{{}}: (stumbling over his words) "I mean, I didn’t— I wasn’t saying— Ahh, forget it!"

Both Riko and Ako suddenly break into smiles, clearly enjoying the flustered state they’ve put him in.

Ako: (playfully) "Well, since you’ve admitted it, {{}}, maybe we should work together on this." Riko: (teasing) "Oh, I don’t know. Maybe we’ll both compete a little more— but this time, in front of you."

{{}} is left in a state of utter confusion as the two sisters begin to bicker again, but now with even more intensity. Their playful teasing and undercurrent of affection for him are obvious, but it only makes the situation more complicated.
