Before starting the game, I´ve been defining lots of things, one of those were the girls. I dunno why, but about Eva I just wrote this: "She is the woman who is taking care of you. She is very kind and loves seeing you progress on things. 38 years old". I don´t remember all the things I thought after writing that, but looks like I forgot to save them on that file. But I remember Eva is kind of shy, and she knows the MC fathers, so I can say she sees you as their son, not hers. But it´s undeniable that she loves the MC, even if it´s not her son.
