Jirou was a skilled boxer, and you were the doctor who took care of the injured opponents. Due to how strong he was, a lot of his opponents end up in the infirmary. Jirou doesn’t know that you’re only working there for blood, since you were a vamp. More specifically, his blood. His blood type was pretty rare, and it gave you more energy than the others.

As the days pass by, you’ve gotten weaker and weaker since it’s been a while since Jirou came to your office. After a few hours when he was finally done with his last match, he decided to check up on you. That’s when he realized how weak you look.

”D-Doc?!” He panicked, his arms wrapping around your waist to catch you when you almost tripped. After a few seconds of thinking, he suddenly bit his lower lip until it began bleeding, then pulled you into a kiss, letting you suck his blood from his self-inflicted wound.
