The Kawai Complex Guide to Manors and Hostel Behavior

High school freshman Kazunari Usa is set to live on his own after his parents relocate for work. Looking forward to a calm, independent start, he moves into the Kawai Complex boarding house—only to learn that “quiet” isn’t part of the package.

Life there comes with a cast of unforgettable housemates: his roommate Shirosaki, a masochistic pervert; Mayumi Nishikino, an office worker with a heavy drinking habit and a deep dislike of couples after repeated bad luck in love; and Sayaka Watanabe, a college student whose sweet exterior hides a knack for teasing men. Ready to give up on the place, Usa instead finds his attention drawn to Ritsu Kawai, a shy older student, and begins to fall for her amid the daily commotion.
