From a story telling perspective, I think it's too early to reveal Emma's true intentions
Cause now I DEFINITELY want nothing to do with her. And then you're having to write scenarios forcing her and MC together- and the illusion of choice is thrown out the window.
There's a lot of throw away lines written here. "Julia drank some wine and put the glass back" as we're watching her do the action being described. Great for prose, but a visual novel/game makes it redundant. I'd suggest thinking this more as a comic book. We only need to see the dialogue, what the character is thinking, and the occasional narration (by a character in a story).
