Oh, so Hui's words were like "it's fine to be who you are regardless of weight", at first I thought he was pointing out that there was no need to do so (in a bad way because he was trying to sabotage her), solely because he likes her like that (and that's what would be important from his pov, not her wishes). Glad to see it wasn't the case and glad to see he's planning to stop being annoying~
Anyway, I'd prefer to pay all my attention to the black-haired guy in the cover, hopefully, he's the ML (she looks so pretty in any way but rn she looks so badass). >U<
