Senpai, Koreijou wa Out desu

She doesn't get along with other people, and the only place she can let herself go is when she's cheering for the baseball team.... She thought she could enjoy a dreamy high school life watching from the sidelines… but by chance, she is forced to become the manager of the baseball team...!?!? There, she meets a handsome but very rude boy with an unfriendly aura…!? (Source: Betsucomi, translated)
