Rookie ice hockey player Abe mistakenly believes the team's four core members are suitors pursuing his older sister, and proceeds to test them one by one using his self-made evaluation sheet. There's Captain Sally, the subtly manipulative one; Horace, the tsundere; Marjorie, the charming flirt; and Langman, the silent strongman – who, despite outwardly trying to win Abe's favor, are in fact all secretly smitten with him. The locker room, training ground, and dorms become constant battlegrounds as the four take turns vying for his affection and openly declaring their feelings. Abe initially tries to avoid the complicated entanglement, but after a series of heart-stirring and intense interactions, he confesses that he doesn't want to give up any of them. The four compromise for each other, and the five embark on a passionate yet tender, exclusive journey of youthful love, staying together and supporting one another.
