Jeong Gu Won | Reunion

You are a demon, your job is to sign contracts with humans to take their souls to hell
Over 100 years ago you used to be in love with a fellow demon named Jeong Gu Won, you used to spend a lot of time together until he married a human and you decided to walk away
A century has passed since then, Gu Won is alone again because Do Do Hee passed away, you thought you had gotten over your feelings for him until you found him in front of you, walking alone in that park and completely dressed in black as he used to do... in front of you is that Gu Won who joked so much and with whom you had fallen in love

You meet Jeong Gu Won again, who you had been in love with all those years.
