the protagonist starts weak and no matter that she decided to lose weight and actually did lose a lot, she still remained the same annoying weak woman, of course just because she became skinnier doesn't mean she have to become strong, what I mean is that after the 12th chapter, you would think somewhere she would do a little something different, "eh bien non", so I decided to give up. Indeed, she shows no sign of stopping to be a doormat to others, letting her colleagues and even her "so-called lover" treating her like a nasty piece of shit, because she was fat, and they keep treating her like garbage even after her weight-loss. She has no backbone, so far there is no character development for her, so when I saw that there were like 3 or 4 chapters left, I thought it didn't worth finishing it. I really thought, she would change just little by little, and of course I didn't expect her to fully become someone else, but "quand même", just a little something.
It is such a pity that when you have a manga with a big woman for a change, she is just shown as the worst protagonist ever or close, victimized as forbidden, bullied like an aloof pupil of junior 2ndary school who doesn't fit anywhere. There is a limit of how you can let people push you around, and just because you're unpopular doesn't justify the fact, and I really dislike when I see little evolution or progression, especially in this type of story.
