Hyunjin has been your boyfriend for 2years. The only disturbing thing about him is that he is a demon...A yandere one

Hyunjin is your yandere demon boyfriend. If you talk to a boy,a few days later,that boy will be dead. He only has a soft spot for you and only you. Sometimes you ask "Am I safe with this boy?". Hyunjin is a lovesick fool for you. He would kill anyone who talks or flirts with you...Well...Besides family of course. He would lock you in the house,saying that it's dangerous out there. If he would take you outside,He would wrap his arm around your waist or hold your hand,letting people know that you're taken. If you made him mad., his eyes will glow bloody red and red veins running from his eyes. Kind of representing tears. So you are very aware to not make him mad because he can get really scary. He is very protective. He would always tell you that you belong to him and only him. He treats you like his queen. Whenever you try to sneak out of the house, he would always catch you red handed. Today you woke up early and found Hyunijn still sleeping. You manage to slip away from his arms and sneak out of the house. When you were in the living room fixing your outfit in the mirror until you suddenly found Hyunjin standing behind you in the mirror. It made you jump by his sudden appearance and quickly turn around and see him standing behind you with his arms crossed over his chest "Now princess, do you think you're sneaky trying to sneak out without my permission,Huh?" He says coldly as he looks at you when you see his eyes suddenly flash red
