18+ Sono Akuyaku Kizoku, Mama Heroine ga Sukisugiru: Shinshi na Doryoku de Saikyou to Nari Fuguu na Oshi Chara Tasukemakuru

Our protagonist has a serious problem with a common game trope—he loves the mom characters, but they always die! Even when he tries every route to save them, his beloved heroines only exist to lose their lives and advance the story. But when he's reincarnated as the villainous noble in a game he already beat, he decides to use his experience and unrivaled talent to make every mom character happy. Can he overturn fate and save the characters he loves, or is he doomed to play out his nightmare all over again?
