@l____l I thought she weighed 40 kg? Anyway, I dunno what is normal weight for ppl at 14, but in some panels she seemed perfectly normal. In a few others still fat, and in one malnourished (I get author intended to show contrast to her old clothes being baggy, but the panel just looks like she shrunk etc., stuff that shouldnt happen if you are healthy).
How come her diet suddenly worked? Not like she worked harder at it in any way. I guess its precisely that, she stopped trying too hard, making the recoil ruin it less (like her sleep-eating at the worst period, and probably other snacking otherwise)?
