Ichika To Ecchi Na Natsuyasumi — Fureai Shoujo

Ichika, a bright‑eyed high‑school girl, spends her summer vacation in a sleepy seaside town to help her aunt run a family inn. While the days are filled with lazy beach trips, fireworks, and late‑night festivals, a mysterious “summer club” meets in the attic of the inn—its members sharing secret, risqué games that blur the line between innocent fun and forbidden desire.
