At fifteen, Hana Tabata has already accepted that she will never experience a memorable high‑school romance. She loves shōjo manga, flowers and all things cute, yet she sees herself as only a background figure: slightly plump, with a round face, glasses and freckles—features that might make her conventionally unattractive. However, when she unexpectedly befriends Yousuke Ueno, a warm and charming classmate, everything changes. His gentle smile and supportive words gradually erode her self‑doubt. As she wrestles with mixed emotions about this new bond, Tabata still does not realize that the love story she has long imagined is already unfolding in the corridors of school.
