Tomodachi no Imouto ga Ore ni dake Uzai

Akiteru believes the "teasing means liking" trope is a lie, as every girl he encounters only shows him disdain. He's focused on joining his uncle's business with his game development friends. His uncle presents a challenge: Akiteru must pretend to be his daughter's boyfriend to secure the opportunity. This forces Akiteru into an awkward situation, especially considering his best friend's sister, Iroha, relentlessly bullies him. The anime explores Akiteru's attempts to navigate this charade, his relationships with the girls in his life, and his pursuit of his career goals, all while dealing with the constant teasing and potential romantic complications.
