About a Love Song, Vol. 1

Band member Hoshina loves music but struggles to write love songs while working part-time at a convenience store. He's drawn to his younger coworker, Seto, but doesn't expect anything to come of it... until the two get caught in the rain and end up spending the night together.

In the morning, Hoshina discovers Seto is a high school senior, and insists that they stop seeing each other until after Seto graduates. Seto wants to explore their relationship further and continues to pursue Hoshina, but Hoshina (awkwardly, earnestly) attempts to keep him at a safe distance. While apart, Hoshina is inspired to write a song about his feelings for Seto, and following Seto's graduation, he sees Hoshina perform the song and the two reconcile their feelings for each other. A sweet, heartfelt love story.
