The story takes place in Sakuragaoka High School. At the opening ceremony, Goda Mio (voiced by Toyosaki Aoi) and Serizawa Haruki (voiced by Suzumura Kenichi) met. In the scattered cherry blossom rain, the figures of the two left a deep imprint in each other's eyes. Afterwards, the red thread of marriage closely linked the two together. They went to school and came home together, ate lunch together, and chatted on the rooftop to pass the time. Although the friends around them thought that the two were already in a relationship, only the two of them knew that there was still an unbridgeable gap between them. Mio is a member of the art club and often immerses herself in her own world when painting. Haruki joined the film research club. With a cheerful and optimistic personality, he likes to get together with friends to discuss the most popular movies at the moment. Are there people in this world who like each other but cannot express their feelings?
