YA book with purple cover

I remember reading this book in ~2018 ish. I literally cannot remember anything about it except that it had a purple hardcover and was about this boy and girl in their high school years. I think it's a friends-to-lovers trope. I want to read it again because I remember showing it off to everyone for how good it was. I hope you can help me.
