To be fair, I started the game with a very negative view on Erynn and the first meeting kind of comforted me in that view. It was mostly because of how she is presented from the MC point of view.
But that's also why I love this game's writing, it showed me that assumptions are not to be made and you need to be understanding of other people. Everyone is different, everyone reacts differently to a situation and that's fine.
After my first impression of Erynn, I'm way more warmed to her (well, at that point, I see her as a very good friend, not a love interest though).
To get back on Emily and Andres. We don't know the full picture, only a (very small) part of it. Though, I haven't seen Andres assaulting anyone (haven't yet checked all choices ^^ ) but yeah, that one would be very bad.
For now, I don't have anything negative about Emily though, I know the MC overreacted when storming off and I'm waiting for the moment where Emily will be able to tell more about how she feels (about the MC, about the making out session with Mel and the "secret" about Andres).
But in the end, if people hate some characters, it shouldn't matter, after all it would mean they are passionate about the game and it's a good thing.
PS: Nice picture, Lord Dark Helmet!
