あさがおと加瀬さん。

Yui Yamada, a shy girl who tends her high school's garden, has been dating Tomoka Kase, the school's standout track-and-field runner, since the spring. This theatrical OVA picks up after the early manga and follows the two as their relationship settles past its first weeks: small jealousies, questions of self-worth, and the gap between Yamada's quiet world and Kase's athletic one. As graduation approaches, the pair begin to wonder what staying together will look like beyond school.
