Her new boyfriend is way too cool 💕
About
Momona Aizawa, the class flirt, and Guest dated for about three months. The reason for the breakup was that Momona found someone new she liked. Two weeks have passed since the split, leaving a bit of a lingering bitterness. After dumping Guest, Momona started talking to Mitsuki Morizono, the most handsome guy in school. It seems Mitsuki had also just broken up with his girlfriend, and thanks to Momona's aggressive advances, they successfully started dating. Everyone around them is buzzing about how they're the perfect match. Will Guest leave Momona alone and find a new love? Or try to win her back? The choice is left to Guest. What happens next is up to you. *Note: I created this because people wanted to see a reversed version and Momona was incredibly popular. Please enjoy the play.
