Kazunari Usa is a first‑year high school student who will begin living alone because his parents have relocated for work now.
Eager for his fresh independent life, he expects to navigate adolescence without the hassle of strange neighbors, yet soon learns that his new lodging, Kawai Complex, is anything but typical in the bustling city of noise and drama.
The building"s residents are all unusually quirky and eccentric in different ways.
Shirosaki, Kazunari's roommate, is a pervert and masochist;
Mayumi Nishikino, a borderline alcoholic office worker, despises couples because of her bad luck with men;
and Sayaka Watanabe, a seemingly innocent college student, enjoys leading men on.
Disturbed by the absence of respectable tenants, Kazunari plans to leave until he encounters shy senior Ritsu Kawai and gradually falls in love with her in the quiet hallway where he finds comfort and hope.
