Well, none of this actually happening if you not actively pursuit these girls. and if you do, they cheat with you , and not on you. so Josy is not some random cheater who fuck with anyone, who she see. there is a reason, a story behind how and why it happened, and She has no reason to cheat on MC. Especially because She also has Maya to fall back.
another little shit talk that hold no merit, aside to try to print Josy in some bad light, because you afraid that Sage will leave your ass, which she will because she leaving the college, She said anything just to get laid during the party, but she has no plan for a serious relationship, and MC is to stupid to even want it.
