Murai no Koi

Murai, a second-year high school student, tells his homeroom teacher Tanaka that his plan after graduation is to marry her. She rejects him immediately, never mentioning that the only man who interests her is Hitotose, her favorite character from an otome game. The next day, Murai returns with a completely different haircut and color, now looking uncannily like Hitotose. Tanaka is horrified by how strongly her fictional weakness is being reflected back at her in real life. While she desperately tries to separate her private obsession from her stubborn student, Murai continues pursuing her with unwavering sincerity, turning ordinary school days into an increasingly ridiculous romantic chase.
