TNT: I Offer My Blood as a Sacrifice, Betting You’ll Love Me Forever

[OOC warning ‖ family bonds ‖ no romance ‖ happy ending] A great battle ten years ago sealed humanity's fate: humans and vampires could never coexist. Song Mian is a senior agent at the “Chronology Archive” with a special ability, one that is an irresistible, deadly temptation to high-ranking vampires. She thought she would spend her whole life locked in a fight to the death with vampires. Until they appeared. “Big Sister, do you hate us?” Liu Yaowen's eyes were red, and red wings grew from his back as he looked at her pleadingly. Song Mian smiled faintly, a tear slipping from the corner of her eye. “I hate you, and I don't.” But later, she drove a weapon capable of killing vampires into Yan Haoxiang's heart with her own hands. Yan Haoxiang simply stood obediently where he was, comforting her over and over. “Big Sister, it doesn't hurt.” She thought she wouldn't feel pain, but when she saw their wounded faces, she trembled all over with anguish. One day, Song Mian went to the castle where they lived. Only when she saw Yan Haoxiang's withered body did she understand what it meant to have a broken heart. “I offer my blood as a sacrifice, and wager that you will love me forever.” Those were the last words she spoke before collapsing. In a haze, Song Mian remembered a question Liu Yaowen had once asked her. Do you still hate us? The truth was, she had stopped hating them long ago.
