Sinopsis of Watari-kun no xx ga Houkai Sunzen
Two years ago, the death of Naoto Watari's parents left him the sole caregiver for his little sister Suzushiro “Suzu” Watari and forced him to move in with his aunt. So attached is he to Suzu that she refuses to join clubs or even date anyone, which has earned him snide comments and the title of “siscon” at her new school. But as long as Suzu is safe and happy, Naoto doesn't care what anyone says. However, her teasing classmates may prove to be the least of her worries. The sudden transfer of a girl named Satsuki Tachibana brings back traumatic memories of her past, a past that she helped make so unpleasant. Unpleasant secrets, unknown to Naoto, begin to surface with her arrival, threatening her new life.
