An adult college student finally lives alone, but the apartment is so close to campus that friends turn it into their hangout. His friend and the friend's girlfriend Himari stay over again, stealing his precious private masturbation time. One day, after breaking up with her boyfriend, Himari comes alone. With nowhere else to go, he asks her to stay. Despite once craving solitude, he now wants to remain beside her, and they have sex until morning. She disappears at dawn, leaving a note apologizing for relying on him and asking him to forget. Unable to do so, he runs after her to confess what must be said.
