Tonari no Hogosha-chan

Riko has spent 12 years at all-girls schools and is now adjusting to university life with male peers. She takes on the role of guardian for Mizuki, a younger boy from the neighborhood whose family is relocating. Interacting with college-aged men feels overwhelming and unfamiliar to her. She finds it easier to communicate with Mizuki, who is kind and approachable. Despite this, she reminds herself that she is meant to be the mature and composed guardian, avoiding any inappropriate thoughts.
