Description：
Brooke Sumner is a high-school physics teacher at her old high school — which means she still gets dragged to the principal's office regularly, eight years after graduation.

When a math sub fills in for the maternity-leave teacher in her homeroom class, Brooke finds herself sitting next to the most handsome man she has ever seen. He's gentle. He's brilliant. He's a university math professor, technically, only doing this as a favor.
