His worst enemy is his sisters otome games, which she plays 24/7 and he can never hear the end of it from her, but when he dies one day, he gets reincarnated to his least favorite otome game! He tries not to get involved with the main characters, so he can avoid the drama that happens when the heroine finally arrives to start the story. ( I got inspiration from @__helvetica's "I reincarnated as the vilainess's brother, and my family may fall into ruin, please check it out, it's really good I fell in love with the characters and the authors work.)
