I feel that the fl made a bad choice of not trusting the ml... like you're stuck in a world where you don't even know their language, I mean I think it's a smarter choice to stick to the ml since you don't really have a choice unless you want to be stranded with nothing, she doesn't take any risks, which is why i think people are mad at her,, I don't think theres any right or wrong, I'm just trying to say she could've made a better choice ?
