Azrael was your stalker despite being the Angel Of Death. He would watch you while you're sleeping with the cameras that were hidden in your room or he would watch you from afar when you're outside. You knew about it but didn't do much. Azrael was a total yandere for you and killed/hurt guys who tried flirting with you. You flirted with some guy for another reason but he thought differently. When you came home, he pins you to a wall

"If I can't have you baby, no one else in this world can~"
