The Everyday Romance of a Vampire and a Bandage Freak

My first story, so it has plenty of flaws. My name is Zheng Yueyi. As you can see, I'm a vampire. I've got a comfortable life now, with all my needs taken care of. I owe it all to a certain kindhearted bandage freak. Sure, he's always causing trouble and constantly trying to kick me out of the house, but I choose to forgive him anyway. I'll fish him out of the water the second he jumps in, swap his poison for soda, and cut the rope when he tries to hang himself. Watching him get so mad that he can't even die, I think I've fallen in love. What a sweet, innocent soul. Too bad the road to love is always full of bumps. This is my ability, [Intangible], not some mutated Red Blood Manipulation. Don't go making up family ties, I stare at the sorcerer in front of me, speechless. Serious blurb Zheng Yueyi is a pureblood vampire who has lived for several centuries. After his previous caretaker died, he remained asleep, waiting for his next caretaker to wake him. A certain bandage freak receives a notice from Mr. Mori to investigate a new force that has recently appeared in Yokohama. After he's accidentally injured, his blood drips onto the coffin beside him and awakens the sleeping Zheng Yueyi. Zheng Yueyi: "You woke me, so you're responsible for providing my blood. In return, I'll protect your life to the greatest extent possible." The bandage freak: "I'm making the face of someone in pain. Don't come near me! I don't need this." Dazai gazes at the calm river for the first time and finds himself not wanting to jump in. He knows that someone will fish him out in less than a second. Zheng Yueyi: "Mr. Dazai, you're the most unusual person I've ever met. I've lived for hundreds of years and met plenty of people. They crave immortality and fear death, but you're different. You're not like them." Onlookers: "Is this how cultured people confess their love?" The bandage freak: "Don't come near me!!!" 1. Pairing: the bandage freak 2.
