Help! I Married a Slut!

Kenji thought his life was set: a good job, a promotion coming, five years married to Airi. Then a man from her past shows up at their anniversary dinner and it becomes obvious he knew her far better than Kenji ever considered. The jealousy that follows doesn't fade. It turns into something Kenji didn't expect to want.

The story follows Kenji as he stops avoiding the questions about who Airi was before him, and starts chasing the answers even as they curdle into something closer to obsession. Airi, for her part, seems to know exactly what to do with a husband who's suddenly interested in her history.

Choices split into routes: one direction of netorase plays out no matter what you pick, while a separate netorare path is optional if you want to go looking for it. The game is built around watching Kenji's control slip a little more with each chapter rather than steering him toward a clean resolution.

Later chapters have kept adding routes and scenes rather than wrapping the story up, so this reads more like an ongoing slow burn than a finished arc.
