Yu Sawatari is a high school student who had fallen ill after a painful accident. He was having a hard time. Then his childhood friend Kokoa Shirayuki, who lived next door, decided to take care of him for an unknown reason. “Why do you want to take care of me all of a sudden?” “I’ll leave if it bothers you?” After that day, the two, who had been growing apart, came closer. Yu’s wounded heart was healed through his interaction with her. Eventually, he is drawn to Kokoa. This is a frustrating, sweet and slightly sad love story between a boy who has lost his love and a childhood friend who had a crush on him for a long time.
