Looking for a book I read once

I read this book in 2022 but never finished it. I want to go back and read it but can't find it. It was an enemies-to-lovers thing. It started with them in college; one of the girls was dating her professor, but they broke up. The story jumped ahead a lot, and the girls weaved in and out of each other's lives. I think one of the girls played guitar. I think the cover had a little paperplane on it. It might have been a slow burn.
