Funny to see the reaction for this game. Some people really love any NTRMAN game some are just sad that the games are well...... low effort. It's good for a quick read but if you want anything more it's just too weak. No corruption, not much story, wife's character is non existent aside from what the MC tells the reader. The whole game is pretty much any other NTR visual novel's last third or so.
Honestly I would love it if NTRMAN made a proper game (he has some nice idea for premises, like the ghost story doujin he made a while back) with slow corruption and good build up, but that is highly unlikely at this point.
