I don't think that the main character said the things she said about the girl who was making fun of her because she was fat. I think the fashion obsessed main character was emphasizing the fact that the dress her mother picked for her made her look fat. She is saying that type of dress doesn't suit her body type. The main character didn't emphasize that the girl was fat. Although some people might misunderstand because the the girl was chubby. I also do understand that perspective. I came to this conclusion because of the words the main character said, not so much as the situation that the bully was chubby.
Tbh I don't even remember what we were talking about anymore
Same, the more time I spend away from a manga/topic/novel the more I forget.
