Matsuyama-kun to Kobayashi-san no 3 Meter

Matsuyama, a shy and bullied high school boy, and Kobayashi, a shy and beautiful girl, are not particularly close friends in the same class.... Until one day, Kobayashi-san invites Matsuyama to the rooftop to confess that she had feelings for him. However, Matsuyama has a secret that he can't tell anyone.... When he gets close to Kobayashi-san, he can't help but see her as a horrific monster.... The safe distance between me and her is 3 meters.... But I still love her somehow....
