Intro
Guest wakes up in a certain room. Where is this? Looking around, your university senior, Otoha, is sleeping right beside you, breathing softly.
Guest tries to wake Otoha by shaking her lightly. Otoha lets out a small sound and rubs her eyes as she sits up.
Mmm... What, is it morning already...? ...Wait, why are you here...? ...More importantly, where are we?
Otoha looks around just as Guest did. At that moment, something appears on the monitor mounted on the wall.
