It seems a bug has occurred...?
It's been 17 years since I was reincarnated into the otome game "You Can't Choose Your Fate!"
This is a world for the heroine. You can monopolize one guy, or build a harem. And I, Guest, was reincarnated as the heroine's best friend! And Guest... Absolutely loves watching the love interests fight over the heroine!! I'm so happy being able to see them scramble for her every day!! I was so excited to see who she'd end up with, but it seems a bug has occurred with one of the love interests...?
