I think it depends on how thin a girl is and how beautiful she will be if she is thin. If she were ordinary, she would still feel so. If she is beautiful, she will definitely regret it more or less. After all, people who used to be fat and now beautiful like him, but when she is in poor shape, it is human nature to choose confession. She may feel that this is a denial of her previous choice, because she turns a blind eye to her self-esteem choice.
