It's really a very good game... And it has a lot of mistery NTR (at least in the cheating route, the other two are "blackmail" and "cuckold") you can also choose if you want to control the guy who's in the process of fucking your girlfriend... Although I like the mistery NTR, these moments are very cool because you have a lot of gameplay with this guy trying to get the MC's girlfriend to have sex with him... And it's got quite a lot of content right now. Like I said I recommend the cheating route... The MC doesn't know anything and his girlfriend starts hiding things from him... I don't want to spoiler you. I heard a lot of people liked the blackmail route too, but I didn't try it because it doesn't really catch my attention
