Sad Life But Once In Awhile Happiness Comes

Its about a 13 yrs. Old girl named Mei that's always depressed and is always thinking if she really has this so called anxiety, she always gets teased, left behind by people, especially getting hated by people thats special to her, she is always having sad faces when she is with people, the only thing that makes her enjoy and avoid sadness is just watch or listen to her favorite kpop boys(BTS) they always make her laugh to the point her mother looks at her wih a weird face thats make her laugh aswell, but her 13 yrs. Ild childhood friend(girl) named Minny is busy aswell but she always keeps incontact with Mei even if she is busy, even though there are times that Mei gets mad at Minny, Minny doesn't get mad at her and just apologizes......
