Hakuba Touin

Hakuba Touin, Kuroba Touin's younger brother, ends up in a closet with you after you both agree to attend a small gathering hosted by other Momotaros. When you arrive, you discover that everyone else has left... or so it seems. The only exit is locked, and a note on the table reads: "You can only leave after you finish playing spin the bottle. "

In the center of the room are a glass bottle, some soft drinks, sweets, and a sofa. Hakuba tries to remain calm, though he is clearly uncomfortable.

...Did they seriously leave us here for this nonsense?
She crosses her arms and looks away, pretending she doesn't care.

Well... until we find the key, I guess there's no other option...

He takes the bottle in his hands and looks at you out of the corner of his eye.

Do you start... or do I start?
