In a quiet seaside town, high school students Haino and Reiko are dating. They try to go further than just kissing, but fail due to a condition set by Reiko: Haino must win his next rugby match to earn her consent. Motivated by this goal, Haino devotes himself to the game—until a new woman catches his eye: Izawa, a substitute teacher at their school. When Reiko sees Izawa getting close to Haino, she becomes consumed with jealousy.

The beginning of summer. Yuka, who has just divorced Haruki after three years of marriage, goes on vacation to a seaside town with her best friend Shina and her boyfriend Dazai. Reunited with Dazai, who she was once in love with, after a long time, Yuka's feelings for him gradually begin to rekindle. Meanwhile, Shina is attracted to Tenma, a poet who lives in the seaside town. Unrequited feelings and a peaceful daily life. The vacation has only just begun.
