I've read about some similar situation on Reddit, lol. The thing is—that's how things often happen IRL, unfortunately. I'd say that this is one of the most realistic NTR games out there. A girl cheating willingly, but lying at each step and getting all emotional and swears how much she loves the boyfriend when she gets caught. Yeah, it describes the vast majority of cheaters, male or female.
I liked this one bad end where the MC just loses it and laughs into her face, I call it AHAHAHAHAH ending. It's also good that you are given a choice to break up with her as soon as you see the first video.
I mostly skipped the last part of the story, though, so maybe there are some additional details I missed. Though the girl acknowledged that she started to bang the other dude of her own volition and enjoyed it, it seems that she really "stopped cheating" at some point. But then, in the end, as I understood it, she banged the netori dude "one last time" to make him remove the videos with her and completely lost herself in sex.
Anyway, the sex scenes themselves are hot and the art is better than anything else AS did this year, so overall it's an enjoyable ride.
