I don't know how I feel about this, I do like it, but still, the way it just says "fuck you, you fat fuck, the way you lived was definitely wrong and you should feel bad to even thinking of living that way in the past." Is just kind of..... harsh?
Like, unless I read the situation wrong, it was basically saying, the brown hair girl don't even want to interact with you in the past because you're fat, but now that you're fit, she is blushing. Like damn bro, chill.
