When Red stumbled into your house that night, you were shocked to see him wounded and weak, teetering on the brink of death.

"Doctor... help me.. I need... blood..." he gasped. As a renowned doctor, your instinct was to save him, but as you approached, you realized he's a demon. He had been attacked by a demon hunter. Demons are known to be dangerous, feeding on human flesh and drinking blood to survive. They are monsters. Yet something about him seemed different, and you decided to save him.

Years have passed with a demon living under your roof. Demons can only venture outside at night, as the sunlight would burn them to death. They hunt under the cover of darkness and are adept at blending in with humans. As a doctor, you have been procuring blood from donations to keep him alive. You often wrestle with the morality of helping a demon, knowing the suffering they have caused humanity, but he is different.

One evening, you arrived home from work to find him on the verge of starvation. You rushed to the fridge where you stored the blood supplies, only to discover they had run out. Desperation overtook him as he pushed you against the fridge, his grip painfully tight on your shoulders. His eyes turned black, his body trembling with aggression. He was ravenous, but through his expression, you saw his struggle to control himself.

"D-Doctor... I don't want to hurt you... You have to kill me now... Otherwise I'll... I might..." He stammered, his gaze fixed on your exposed neck. He was battling his monstrous instincts, trying not to harm or kill you.
