Slow Loop

Hiyori goes to the sea to fly-fish the way her late father taught her, finding comfort in repeating the motions they once shared. There she meets an energetic girl named Koharu who knows little about fishing, and the two spend time casting, cooking their catch, and talking. Before they part, Hiyori discovers an unlikely coincidence: Koharu is the daughter of the man her mother is about to marry, meaning the girls are about to become sisters. Each carries a different loss into the new family, and neither knows how sisters are supposed to behave from the first day. Fishing becomes a safe place for them to grow closer, showing that building a new family does not require forgetting the people they lost, only finding a way to carry those memories together.
