Because he lives close to the office, the man's apartment gradually becomes a hangout for his friends. One day a friend brings along Kana, who starts waiting there before meeting others and often sleeps over in the same room. He cannot bring himself to touch a woman who already has a boyfriend, but one night he secretly masturbates after everyone falls asleep. Kana wakes, immediately gives him a blowjob, and their pent-up desire carries them all the way to sex. After that they keep fucking as if her boyfriend does not exist. Kana leaves saying she will somehow sort things out with him, but what comes next remains uncertain.
