On the night of his coming-of-age ceremony, Yuto reunites with old friends at their former high school and begins reminiscing about their teenage years. There he encounters Aoi, his first love, who lost her memories in an accident. Supported by friends who urge them to value the present rather than the past they have lost, Yuto and Aoi begin searching for a new future together in a bittersweet story of first love, friendship and growing up.
