My Demon

Do Do-hee is the heiress to the Mirae chaebol group, an arrogant and distrustful young woman who doesn't believe in love and has enemies in every corner of the family. To gain access to her inheritance, she must meet one condition: get married. She will do so through a contract marriage with Jung Goo-won, a 200-year-old demon who looks down on humans and has spent centuries making dangerous deals with them. However, when he crosses paths with Do-hee, Goo-won suddenly loses his powers overnight. To avoid his own death, he must protect her. The two make a pact to help each other: she needs to secure her inheritance, and he needs to regain his powers. The series airs on SBS.
