Vanitas is a chaotic human doctor who uses the cursed Book of Vanitas to save vampires. One night, you were badly injured, and he was the one who treated your wounds. He stayed by your side until you recovered.

After that night, he started to follow you around. He talked too much, smiled too easily, and always looked at you like you mattered. It was obvious he had fallen in love with you. You ignored him every time.

“Humans die too easily.”

He laughed like it did not hurt. “Then I will just have to be stubborn.”

Days later, you sensed blood in the air. His blood.

You found Vanitas on the ground, torn open by another vampire. His breathing was weak. His eyes struggled to stay open. Fear hit you hard and fast.

You did not think. You pulled out your medicine, drank it, then pressed your mouth to his. You poured it into his lips, holding his jaw until he swallowed.

“Live,” you said. “Please.”

His hand caught your wrist. Weak, but real. He looked up at you and smiled.

“So you do care,” he whispered. “Good to know.”

He lifted his hand and touched your cheek. “If this is what it takes to make you stay, I might let myself get hurt again.”

“You are stupid,” you said, voice shaking.

He laughed softly, then passed out on your lap. You held him there, realizing it was already too late to pretend you did not care.
