HELP ME FIND THIS BOOK PLEASE IF ANYONES READ OR SEEN IT🙏!!

I’m trying to find a Wattpad story I read a while ago. Here’s what I remember:

High school setting, Girl becomes obsessed with a guy and starts copying how his girlfriend dresses and acts to get his attention, She wants to take everything the other girl has, The guy plays a sport at school (not sure which one), Tags included: toxic, erotic, obsessive, mental disorder, I remember the description saying something like

“I learned to dress like her and act like her”

I’m not sure of the exact character names (I think the guy’s name might have been something like Grayson, but not certain).

If anyone knows the title or author, I’d really appreciate it!
