I don't think Maya and Josy are bad characters, but I do think the revelation of their relationship was poorly done. As Maya is talking to Josy the MC's cum is on her back lol. Josy couldn't be bothered to call Maya to tell her she was coming to college.
The lying stuff is werid, firstly the MC is going after like 6 different chicks at once, so him getting that pissy upset is a little much, but also Maya told the MC the biggest part of her self that she's into women, why not in that moment also just mention your dating a girl? Especially when she's already ask the MC to never lie to her?
