Kengo Kosaka (Kento Hayashi) is a young man who looks very gloomy. He suffers from severe mysophobia, so he cannot interact with other people normally, which makes him feel very painful. One day, a mysterious man found Kengo and gave him a special commission. A female high school student named Sasaki Sei (Nana Komatsu) was unwilling to go to school because of her visual phobia. The mysterious man hoped that Kengo could help the girl. At first, Asheng was very resistant to Kengo's attention, spoke badly to him, and had a very bad attitude, but soon, Kengo, who had a similar experience with Asheng, understood that this aggressiveness was just a way for Asheng to protect himself, and he was very familiar with this way. Gradually, the distance between Kengo and Asheng gradually closed.
