I'm looking for the name of a pixel-style erotic game that was likely made with RPG Maker or a similar platform.
The game is in the NTR genre. The main character, a man, moves to a new town with his girlfriend, who has purple hair. They plan to get married, and they have agreed not to have sex before their wedding. The protagonist gets a job at an office near their house, while his girlfriend commutes to a neighboring town for work.
As time goes on, the girlfriend starts cheating on him. One of the most memorable scenes is when the protagonist catches her having sex in a swimming pool, where she was doing it to make money. The game has a rainy atmosphere throughout, which adds to the melancholic and emotional tone.
There is a bad ending where the girlfriend completely leaves him. The game had pixel art and a rather emotional, somewhat dark story.
