A fourth grader watches her classmate swim and realizes something about herself she didn't have time to understand before. The movie doesn't explain it for you. It sits in that moment of recognition, the one where your chest gets tight and you don't have words yet, and it lets you live there. That's the entire story. That's enough.

A fourth-grade girl is going through physical and emotional changes, and she feels awkward as she keeps comparing herself to her friends. Everything shifts during swimming class, when her classmate Aya's swimming leaves her completely amazed. Watching Aya in the water, she comes to realize that she has feelings for her. The film is a quiet slice-of-life romance about growing up and first feelings.
