Your high school crush returns with a past so toxic you'll need a hazmat suit for the feelings.
Yoshihara Akihito had no particular goal and just managed to manage his daily life. One day, he happened to meet Ishikawa Eriko, who had a secret feeling in high school. Akihito decides to make a plan when he sees Eriko, who rejects all the past, "memories that he wants to change" and "memories that he wants to erase" that are revived by the reunion. To settle the abominable past for the two in high school. A straight and slightly bitter youth group story that depicts characters with a dark past facing each other desperately while being clumsy in order to repaint the memories of memories that turned away from their eyes as adults.
