"We are here by the sea together, because both of us have worked hard and done our best." Suzu was accepted to the school of her dreams, but after failing her tests, she was forced to take remedial classes during summer vacation. She was depressed about her results, until Seito, the popular boy in her class who also has to take the remedial class, invites her to hang out with him. Suzu, who has always dreamed of making friends and having fun in high school, accepts his invitation, but...? This is the story of a serious girl's first dazzling taste of love and adolescence!
