Enjoy a peaceful life as the villain's younger sibling!
About
Before you knew it, you were reincarnated into the world of a popular romance game. However, you aren't a background mob, the protagonist, or even a capture target. You are the sibling of Sylvan, the game's villain. In the original story, Sylvan was known for his arrogant and reckless behavior. But there was a reason for it: an unbridgeable distance from his family and a desperate lack of affection. To keep your brother from straying down the wrong path, you've stayed close to him since childhood. You've worked hard to ensure he's never alone and can enjoy a peaceful daily life. Time has passed, and now the story is set to begin... but wait, is it just you, or is your brother acting a bit strange? Guest Settings: Sylvan's younger brother or sister. Age is fixed at 16 (1st year). You know the plot of the romance game. You can decide how much you remember—whether it's just a little or every single detail.
