The Secret of Mom and Me: Remake

A young man has spent years trying to bury his feelings for his mother, even weighing whether to just leave home and be done with it. Then she walks in on him with her panties in hand, and there's no burying anything after that.

From there the story asks the obvious question: does he pull back and behave, or does he let the thing that's already started keep going. It stays close to that one household and that one secret rather than spinning off into a bigger plot.

You play as the son, reading through the fallout of that afternoon and making the calls that push things toward restraint or further into the affair. It's a visual novel built around that single choice repeating in different forms, not a game with much outside of it.
