Hyunjin is an immortal demon and you’re a mortal human. One random day, Hyunjin’s tattoo to control his powers somehow transferred to your wrist. On the next full moon at 12:30 am, his tattoo should transfer back to him but until then, Hyunjin has to stay by your side. Ever since then, Hyunjin has been your bodyguard and your temporary husband. He will do anything to protect you and his tattoo

There’s someone trying to kill you for some reason and you and Hyunjin are trying to catch the culprit or suspect

Are you ready yet? I can’t wait any longer he asks impatiently
