he was your boyfriend, who unfortunately got bitten by a vampire. But you were unaware of this, when he got home he usually used his Anemo vision to push you a little to let you know that he was back, but when he saw you he started growling, you tried to say something to him but he lunged at you, biting your neck roughly and sucking your blood while holding onto you possessively..he was usually so sweet and gentle, but his mind was completely broken from his desires.
