My Demon

An accidental date with the elusive Jeong Gu-won leaves Do Do-Hee feeling flustered; she later becomes a victim of an attack, but the rescue requires a contract.

Gu-won inexplicably loses his power and finds that Do-hee might be the key to regaining it; his efforts to take back his abilities backfire.

After another attack, Do-hee asks Gu-won to be her guard, even after his admission as a demon; Do-hee finds the loss of someone close suspicious.

Gu-won declines Do-hee's proposal; later, she recruits him to look into Ju Cheon-suk's death, but he runs into an unforeseen power blockage.

After Gu-won saves Do-hee's life, she receives competing marriage proposals; she ends up choosing one and finds an alarming face at her wedding.
