This is not graham's fault what so ever. He didn't choose to be hero, so I don't understand why graham has to suffer losing his loved one? It would be one thing if graham couldn't protect her but that's not the case at all as he does come and save her. Also wanting to be with someone DOES NOT mean you don't love yourself, Luisa loves herself very much as she wanted to originally leave graham because she thought he would abandon her, she didn't wait like a a desperate girl for him she instead left and thought about herself! It's not wrong for anyone to be with someone who can protect them and in this story so far, graham have not let her get hurt and it's pretty clear he has no intention to let her get hurt. It is also not wrong for her to find happiness WITH graham either, because graham makes her happy. So you are free to ship or not ship whoever you want, but I don't think there is anything wrong with Luisa finding happiness with the one she loves.
After reading the raws I just don't want her to end up with graham. I mean she almost got raped like fuck no girl and ig not knowing the context of it makes it hard who's to blame but her being around graham puts her in dangerous situations I mean girl think of urself first no matter how much u love that person u need to think of ur safety. She has gone through so much bc of her love for the mc that I want her to love herself first and think about herself. I was really hoping and looking forwarded for her to find her happines but in the end she went with graham. Man I wanted her to be happy but if her being with graham is what makes her happy then ig I will come back when it ends to see how it turns out.
