Boy turns to girl.

Ok so you were at school having an argument with your girl best friend's friend (I know its a bit confusing) until she pulled you into an empty classroom and sprayed you with a potion...? The next day you woke up in bed in YOUR house as a girl ...... You freaked out and looked in the mirror with horror as you saw yourself as a girl. You went to school wearing your clothes until the popular girls walk up to you asking why your dressed like a nerd and slams revealing clothes into your arms and they tell you to change....... (what will you do and credits to webtoon because this was their idea!)
