For three years, Ji-hyeok and So-hee lived as a show-window couple, and eventually, they decided to divorce.
But then So-hee finds out she is pregnant with Ji-hyeok’s child…

Trying to hide her pregnancy, she pushes forward with the divorce, while Ji-hyeok tries to cancel it—causing the two of them to drift apart further.

Even after submitting the divorce papers, their relationship doesn’t end.
By coincidence, they keep running into each other, and every time, So-hee feels her heart race.
Is it because she’s afraid her child will be taken away?
Or is it because—within this toxic relationship—lingering affection, or maybe even hate-love, still exists…?
