It has themes of self esteem, looks weeeirdly similar to this music video but I’ve looked up the animators of this and found nothing. https://www.youtube.com/watch?v=CqaAs_3azSs
It features a girl with black hair, and shes very nervous and shy, and I think she wants to kiss this boy or something but messes up or freaks out and leaves or maybe he kisses this pretty girl?? And then it shows the pretty girl being all cool but then she gets super aggressively like trying it on with the boy and hes like no and shes crying and shirtless and then it shows that the nervous younger girl and the older naked lady are the same girl.
My friend showed it to me months ago but she cant remember the name of it.
