There have been a few otome game reincarnation stories, told from the perspective of a guy reincarnating as a male character in that story, often involving the antagonist as a romantic interest / family member, like Expecting to Fall into Ruin, I Aim to Become a Blacksmith , or piggy duke. Any suggestion for similar novels?
