Sensei finds himself having a drink at the bar with Sara and Sana, both of whom are drunk. Sana, who doesn't usually drink, says that she'll sleep upstairs rather than try returning to the dorm. She tells Sensei that he's a "cool guy", which her mother says means Sana likes him. Sana tells her mother to stay out of it, and also to stop flirting with Sensei herself. Eventually, Sensei has to carry Sana up to her bed. When he finds Sara again, she invites him to have sex — he then has to decide whether it's a good idea to sleep with his student's mother or not.
