Fifteen years ago, Eunseol was accused of attempting to murder her co-star, Yi-hyeok. Her career ended and she hasn’t known peace since, all because her mother made her take the fall for her brother so he could keep acting. In present time, Yi-hyeok is trying to find a way to displease his grandfather in order to change his inheritance and decides to approach Eunseol with an offer for a fake relationship. All they have to do is be convincing… so convincing that even they may start believing it.
