So one can only imagine when he found the approval of fellow classmate, Sei Mishima, in his freshman year, the two became inseparable. Now in college, their relationship starts to move from friends to friends-with-benefits, as they quickly discover their apartment isn't the only thing that's a tight fit. With Kanao's cravings for attention and danger, their activities may be a bit loud for their neighbors. Their neighbor Konno, however, may be a little more interested than annoyed with the couples constant nighttime noises?
