Contemporary plus sized heroine/hurt by hero in high school

[Lynn]

All I can recall are bits and pieces. She was now completely comfortable in her curves and the hero is trying to make amends for his behavior. They both run at night. She is in a big career. Ugh I hate when I cannot recall. Read it several years ago, in physical book form.

I'm not sure if the hero and heroine run at night in this - it's been a few years since I read it - but the other details line up with Here’s Looking At You by Mhairi McFarlane.
