This is a 25-minute film that looks like Studio Deen spent the entire budget on watercolor backgrounds and forgot to write a plot. That's not a complaint. Eri and Haru's summer feels lived-in because every frame is so deliberately beautiful that the mundane moments, sitting in a room, humming a song, missing each other by inches, become the entire point. The pacing lets you breathe into silence instead of filling it, which is the only way a story about two girls learning to want the same thing at the same time could possibly work.

Eri, a girl who prefers to stay indoors, crosses paths with Haru, an energetic and eccentric transfer student. Eri once loved to sing, and Haru adores her singing. The two end up sharing a dormitory room, and Haru causes one headache after another. When Haru pokes through Eri's laptop and finds out that Eri composes music online, Eri is furious. Haru, taken with that music, wants badly to sing with her, but Eri refuses. Over one summer of high school, the two girls orbit each other, and their feelings sometimes line up and sometimes miss each other entirely. The result is a slice-of-life film built around music.
