Saika and Kenichi, who had been good friends since childhood. Saika stayed in her hometown, while Kenichi moved to Tokyo for work. The two, who reunited for the first time since their coming-of-age ceremony, were aware of each other along with their nostalgia. That's because as they entered adolescence, they became aware of each other as the opposite sex... However, because they didn't want to break their relationship as friends, they didn't convey their feelings of "like," and as they grew up, they became estranged. Time spent together for the first time in a long time. A fireworks display that elevates their feelings. What will be the end of the two who had 'mutual unrequited love'?
