I've been looking at the latest reviews and it's not fair to give low scores just because Mrs Parker is a slut. It's normal to feel uncomfortable, but it doesn't make sense to turn it into a bad evaluation.
People screaming ntr here are also not normal because our main character was not cheated in any way. The only thing that hasn't changed anywhere in the world is that Mrs Parker is a slut, but she's not a lover right now, so her sluttiness cannot be considered ntr.
As for Evelyn she's still a virgin dammit, she's never had anything physical so she's not ntr.
Riley is a normal girl with a sex life, not enough to call her a slut. Moonsong is also a normal girl with a normal life.
Actually, the main problem here is our main character. Every woman around her is an adult with a past life and sex experience, but our main character is a virgin and a teenager who gets hard when he sees a piece of breast. That's why he stands out as a passive character in the story, if this man was a little more established character, he would not attract so much attention. Another problem is that people are used to playing unrealistic VN. These games, where almost every girl is a virgin Virgin Mary, have created the wrong perception. Thus, players were stunned to see a real-life character in front of them.
