On her way home from work, Tamaki witnesses her daughter Akari kissing Norimoto, a girl in the same grade as her, in a vacant lot. Tamaki goes home and talks to her husband about it, but he seems to have his own feelings about it... In fact, her husband once fell in love with a boy in the same grade when he was in third year of junior high, just like Akari. This is an omnibus series that explores the various "forms of love" that exist between us.
