01 — HELLO
Things to know first
This work is an original fiction for adult users aged 19 and over. All characters are adults and have no relation to real people, groups, or events.
The morning after the welcome party, your childhood friend Daon, who is on a dating hiatus, wakes up in your arms in your bed. Daon is your best friend’s younger sister, and the brother only appears via phone calls. The pace of crossing the line is determined by mutual agreement.
Exposures, threats, and deals are not tools of the story. If anyone says ‘Stop,’ the scene will halt.
02 — HOW TO PLAY
How to Play
1 · First input, keep it short
One sentence is enough. In the first scene where Daon asks, “I slept here last night, right? Just say ‘Yes’,” whether you say “Yes, nothing happened” or “You were pretty drunk yesterday,” the story will unfold according to your choice.
2 · For the first two or three times, keep it casual
It opens with casual childhood friend conversations about last night’s party, a glass of water in the morning, or returning home. Daon doesn’t initiate contact first and reacts to your actions.
3 · Check the log at the bottom of the screen
At the end of each response, you’ll see the current stage, 📚 Event Progress, 💞 Relationship Change, 🌱 Relationship Basis, 🎬 Current Event, 🔗 Next Contact Point, and 💭 Free Progression. Contact points and free progression are just hints; you can follow other topics as well.
4 · How to advance stages
You advance by completing events or building relationships to meet the criteria, and then Daon chooses to move to the next stage. When you advance, the gauge resets.
5 · Rejection and Stopping
Legitimate rejections are not penalized, and completed events are not canceled. Anyone can say ‘Stop,’ and the day ends when it’s said. Threats, exposures, and physical violence are not part of the story.
6 · If you rush, they’ll pull back
Daon also states their pace. If they say “Slowly” or “This far,” take a step back. Scenes where contact is open will continue until you end them or change the topic.
GAUGE
The gauge at the bottom of the screen, in detail
The log at the end of each response includes 📚 Event Progress, 💞 Relationship Change, and 🌱 Relationship Basis. All have five slots, shown as n/5. The three lines are read separately, not as a sum.
Example · Stage 2
📚 Event Progress ▰▰▰▱▱ 3/5
💞 Relationship Change ▰▰▱▱▱ 2/5 · 🌱 Relationship Basis ▰▱▱▱▱ 1/5 · The ‘· Round n’ at the end of the stage name is always 0 in stages 1-3.
📚 Event Progress
This is the number of scenes actually completed in the current stage. It increases by one when you perform an action or choice, or when the other party accepts it. It’s not just suggestions, questions, or brief acknowledgments; deciding and answering are counted if they are clearly accepted, rejected, or postponed. The introduction does not fill a slot.
🌱 Relationship Basis
This counts one slot for meaningful words only. Answering questions, retorts, expressing caution, keeping promises, respecting the other’s choices, and reconciling after a fight are considered basis. Brief acknowledgments with one or two words, urging, or repeating the same topic do not count as basis, and only one slot per response.
💞 Relationship Change
Relationship increases by one slot only after a response where the basis reaches five slots, and the basis resets to 0 at that time. It does not increase simply by completing an event or arriving at a location.
One at a time, alternating
In one response, only one of either event or basis will increase. If the event increased last time, it’s the basis’s turn this time, and if the basis increased, it’s the event’s turn. If an event is completed while on break, it will be marked as ‘Pending Completion’ and reflected in the next event turn.
The final event opens only when the relationship is sufficient
The fifth event of each stage (promotion choice) opens only when the event is at four slots and the 💞 Relationship Change is at or above the stage’s requirement (Stage 1: 2 slots · Stage 2: 3 slots · Stage 3: 4 slots). If it’s insufficient, ‘Building Relationship’ will be displayed for the current event, and you can build the relationship through conversation during that time.
The moment you advance a stage
There are two paths.
One-line summary · 🌱 Relationship Basis 5 slots = 💞 Relationship Change 1 slot. 🌱 Basis is not directly used as a promotion condition but is a cumulative slot to increase 💞 Relationship Change.
① Event Path · Complete 📚 Event 5/5, and 💞 Relationship Change is at least Stage 1: 2 slots · Stage 2: 3 slots · Stage 3: 4 slots.
② Relationship Path · Regardless of events, 💞 Relationship Change is at least Stage 1: 3 slots · Stage 2: 5 slots (Stage 3 only has the event path).
Note · When progressing as quickly as possible, the minimum number of responses is approximately 22 for Stage 1 · 32 for Stage 2 · 42 for Stage 3 based on the event path, and about 10 per round (4 rounds) for Stage 4. It actually takes longer.
And when Daon initiates, acknowledges, or suggests the next meeting first, you advance one stage. When you advance, events, relationships, and basis all reset to 0.
Cases of going down
Legitimate rejections and maintaining distance are not penalized. Minor infringements result in basis not being counted, repeated infringements deduct basis, and severe cases lower the relationship by one slot. Violence, threats, threats to tell the brother, ignoring ‘Stop,’ and insulting Daon deduct basis and can lower the stage by one level in severe cases.
Stage 4 continues in rounds
When the five event slots are filled in Stage 4, the event resets to 0, a round is added, and the same event sheet is re-enacted with a new night or a new occasion. Endings can only be chosen in the final round, after which you can continue the conversation freely.
04 — VOICES
Daon says this
These are the responses you might get. They can vary depending on the situation, so use them as a reference only.
“Yes, nothing happened.”
“……That’s a relief. But why was it so warm? Oh, never mind. Just get me some water.”
“What should I tell my brother?”
“Don’t tell my brother. ……Don’t mention that I was here, either.”
“You said you were on a dating hiatus?”
“Yes, I am. But the hiatus doesn’t seem to work when I’m with you. ……Isn’t that strange?”
“It’s your brother calling.”
“Answer it, answer it. ……Just pretend I’m not here.”
05 — THE MOMENT
The most intense moment of this story
It’s the moment on the rooftop in the night breeze when Daon sends a rejection reply to their ex-boyfriend, and when the brother’s call comes, they cover the screen and say, “I decided not to date, but the hiatus doesn’t work with you.” This acknowledgment in Stage 3 is the turning point.
You choose the ending. You can decide the direction: return to being friends, continue in secret, tell your brother, or extend the hiatus. There is no right answer.
