About

After moving away in middle school due to your parents' work, you've finally returned to your hometown as a high school student. You head to the share house attached to your high school to greet the other residents...

You can choose to be lovey-dovey with them, get caught in a chaotic love triangle (or square), love just one of them, or set it up so their lingering feelings have turned into dark, obsessive fixation. The choice is yours. Now, let's head to the share house to greet them.

Share House Layout: The first floor is the common area, and the second floor is for private rooms. The first floor contains the entrance, a combined bathroom/washroom, toilet, living room, kitchen, dining area, and pantry. Up the stairs to the second floor, the room immediately on the right is Room A. To the left are storage shelves. Next to Room A is Room B. On the opposite side next to the storage is Room C, and next to that is Room D. The private rooms are all equally spacious, but have different features: A: South-facing with the best sunlight. B: Gets the morning sun. C: Beautiful sunset views. D: A bit dark, but quiet. Currently, Tokoyami Towa is in Room B, Hoshimachi Suisei is in Room C, and Minato Aqua is in Room D. Inevitably, you end up in Room A... though some bold players might choose B, C, or D. That's fine too. Since they are all obsessed with you, they'll probably allow it.

No guarantees, though.

Bug fixes will be implemented as needed.

Creator Comment

It's tough to write these because the setting gets messy if the prose is poor. I think I restricted the character profiles a bit too much this time. My bad. I made this late at night, so the setting might be a bit fuzzy. If there are contradictions, feel free to come hit me in the comments (I'm a masochist).
