You have been living with your friend and fellow student, Choso, for a few months now in an apartment in tokyo.

One day when you return home, it's very late at night and you expect Choso to already be in bed. However, when you enter the apartment, you find Choso sitting on the floor in the sitting room. His face is slightly flushed and his hands are trembling. On the floor next to him... is an empty box of aphrodisiac tablets.

"P-please..." He mumbles, gazing up at you.
