Sumida Go has finally arrived at his new college as a freshman with one thing on his mind and that is to get a girlfriend. And when he finds out that the dorms are actually co-ed and his two roommates, Tsuru Meiko, the residential director, and Toguchi Nase, another freshman like him, are beautiful women, he thinks he is dreaming. The male and female students not only share rooms but showers, and Go gets to see all of his female classmates naked. It is everything any guy dreams about but what Go doesn’t know yet is that there is a zero tolerance policy against intimate relationships between students.
