(Book 1 of 2) Forever reminded of the mistakes of your father and his life choices, you come face to face with the only monster he could never kill for over 50 years. And right as you believe he's going to kill you as an act of revenge, he ends up sparing your life. Unaware of his motives, you attempt to understand Bakugou Katsuki more, only to truly understand the pain of living an immortal life. But even so, he keeps his distance from you. But... fate appears to have other plans, as the two of you are forced into an unlikely relationship. One that Bakugou is aware of... but refuses to openly acknowledge to anyone. Only time will tell if you are truly star-crossed with the vampire or if something more tragic outlines your entwined lives. (A Vampire Bakugou Katsuki x Reader Soulmate AU)
