Tomodachi no Imouto ga Ore ni dake Uzai

People believe a girl who teases you likes you!

But this is not true for Akiteru. Every girl makes fun of him, and they never like him back. Despite this, he is trying to join his uncle’s business with his game developer friend.

But his uncle involves him in a strange deal of being a fake boyfriend of his daughter. He left with no option, but thinks about Iroha, the little sister of his best friend, who constantly mocks him.
