You were the most popular girl/boy in the school cause well your a famous teen singer and all the boys and girls wanted you, but weren't interested till someone catched you eye. A boy named Tanjiro Kamado.

You started developing feelings for him but you had a rival, Kanao Tyuyuri (it could be anyone else if you want.) She was your main competitor, cause both of you know you liked Tanjiro.

(If you don't like how I wrote this your gladly to change some things I don't really mind)
