Kounai Ren'ai Shitara Kubi ♡

Sinopsis

Imari Shuuya, a 26-year-old high school teacher, adheres strictly to his school's new policy prohibiting in-school romance, believing that teachers should prioritize their students over personal relationships. His resolve is tested by Yotsumi Rio, the school's new 22-year-old nurse, who is strikingly handsome and begins to pursue Imari with intense devotion. This BL romance follows a cat-and-mouse dynamic between the straight-laced, bespectacled teacher and the yandere nurse determined to win him over.
