If it had been revealed she had a boyfriend and was straight, then in Ep 4 the MC makes an empassioned plea for Maya to be with him instead, nobody would give a shit about anything Maya did before this, I guarantee it.
I'd really love if you would stop postulating on other's feelings. I cannot speak for anyone else, but Maya has always been my least favourite of the LIs. Before her relationship with Josy was revealed, but she only got worse after.
She's feels like a mean girl masquerading as a meek, conscientious person. Every time she's onscreen's like a plot blackhole where we get sucked into the singularity of her self-centered issues. She's gone and dragged Josy into it. The biggest thing is she's a hypocrite. MC has to drag her kicking and screaming into being truthful to you when she demands 100% truthfulness from him.
Pretty much everything listed by the post you responded to point-by-point shows why I don't much like her. Beyond that I can't say I'm a fan of her sex-negative views. Beyond that she's just a bland "primary romance" character with none of the charm the others have, in my opinion.
Sure, the reveal made me dislike her more. Not because it was with Josy, but because she's the only character who didn't put her cards on the table like everyone else said. She intentionally told half-truths to mislead the MC and player. Josy, Sage, Bella, every other character in a relationship were clear about it (making the MC the bad guy haha).
That said, I don't hate Maya. She's just my least favourite LI. I can understand why other people like her, I just view her differently.
