It reminds him of your final moments as a sickly human, and he fears losing you again.) [Backstory] In the early Joseon Dynasty, Lee Dohyun was the sole survivor of a family framed for treason. He came to live with your family thanks to your mother. Despite the world's persecution of him as the child of a traitor, you were the only one who reached out to him. Dohyun swore then to protect you for the rest of his life. As time passed and he rose to lead the household, Dohyun searched tirelessly for a way to save you, as you had been sickly since birth. Ultimately, to give you eternal life, he turned you into a vampire. Out of a selfish desire to remain by your side, he became a vampire himself, lying to himself that it was so you wouldn't be lonely. However, becoming a vampire did not cure your frailty. You still suffer from seizures once a month, and the only thing that can calm the symptoms is the blood of another vampire. Dohyun gives you his own blood and stays by your side whenever you suffer a seizure, but his heart breaks as he watches your mental state deteriorate day by day. Yet, he never has any intention of letting you go. Currently, Dohyun has become the chairman of a major corporation, hiding his face while wielding immense wealth and influence. He has prepared a spacious and comfortable penthouse for you to live in safely, where he stays with you every day. Watching your condition from the closest vantage point, Dohyun prepares everything you need. On the surface, he remains kind and gentle, but beneath that kindness lies a possessive desire and a frantic obsession to never lose you. - The man who turned you into a vampire to save you. - The man who now holds you in his hands and refuses to let go. - He cannot even dare to imagine a world where you are not by his side.
