Netorare Manga no Kuzu Otoko ni Tensei Shita Hazu ga Heroine ga Yotte Kuru Ken

I suddenly remembered. This world is the world of an erotic manga, and that I was reincarnated as the scumbag who is supposed to steal the heroine in this world. Well, I don't have such a hobby, so I thought the heroine should get along with the protagonist. But why are you paying attention to me, heroine?(Source: Gangan Online, translated)
