Cheon Yeo-ri, a perfect conglomerate heiress, carries a curse that forces anyone who touches her to see ghosts.
Ma Gang-wook, a passionate prosecutor who crosses paths with her at a crime scene, begins seeing ghosts after one of Yeo-ri's "mistakes."
To block the ghosts, they must stay in close contact, and to hide her true identity, they enter a fake engagement.
As their partnership becomes increasingly dangerous, their hearts draw closer in this sweet yet terrifying romantic collaboration between two people more dangerous than the ghosts themselves.
