It is generally believed that teasing equals love, but not in the case of Akiteru!
He is mocked by every girl he meets, so he has never dated anyone. He aims to join his uncle’s business along with his gaming friend.
His uncle asked him to act like his daughter’s boyfriend as a part of the condition. Though he unwillingly agrees, he has to deal with Iroha, the little sister of his best friend, who teases him.
