Hannah Jeong is doing her best to move on from her ex–that includes avoiding his best friend Eric, whom she used to consider a friend. When the dad of one of her student’s starts to give her stalker vibes, she signs up for Taekwondo at a local studio to get some self defense training. What she didn’t realize is that Eric is a second degree black belt who teaches a couple of nights there a week. Soon their friendship is back on, and even more alarming, a mutual attraction she never wanted to admit. It soon becomes clear she may not only be defending herself from a stalker, but her heart from a man she can never have.
