1. She still caught feelings along with the MC it wasn't just the MC intiating interactions between the two.Ok, but you didn't answer any of my points:
Maya lied to be on equal terms, not to take advantage.
The MC didn't really care about what was being lie, so the lie is not significant.
MC doesn't need to lie couse it's a porn game so his behaviour is going to be accepted. Maya is simple more tolerant with the MC flaws than the MC.
And there is another point. You actually have the option to lie. We are simple considering the worst posible path for Maya but it could be way worst. The MC liying and having sex with not two but many girls.
I find the worst cheater here is the MC. Maya could have lie but the MC is an hypocrite, he could fuck all what he wants but as soon as someone fuck behind his back he get angry.
2. The MC did care about Maya lieing after she forced him to be 100% honest which he does by telling her he's going on a date when he goes home.
3.Yes it's a porn game but in your same logic Maya doesn't need to lie because you're still fucking maya either way even if she was currently on another guys cock you taking another hole thats porn logic. But because it's story based she did lie. And in that scenario even in the real world. MC has no reason to lie to Maya as they are not even close to being in a relationship atm.
4.Yes you can lie if you want but it's up to you to decide. And im also not painting the MC as the almighty righty.
I'm, painting him as why he felt that way and why i think Maya was a greater cause then Josy.
Because she forces him to be crudually honest with her from day one but isn't ready to do the same which Maya admits later on she should have.
I'm not calling Maya the devil I love her and all other LI in this game except maybe Jill I don't hate Jill but I don't really like her.
I was simply answering the question given as to why the MC freaked out.
