The legitimate daughter is used by her family as a substitute bride and sent to an old vampire noble household. She expects to marry a perverted seventy‑year‑old m
onster. But when the door swings open, a devastatingly handsome vampire heir steps out. She fears him, avoids him, and calls him dangerous. Yet he closes in on her step by step, shielding her behind him in front of everyone. She thinks she has walked straight into a tiger’s den. Only later does she realize he is not the greatest danger — it is all those who seek to push her into the abyss.
