A girl accidentally transmigrates into a vampire novel and is bound by a shared-fate pact with a half-vampire boy. She must stop him from making a sacrifice, or both of them will perish. The boy carries a forbidden curse; whenever feelings of affection arise in his heart, he suffers excruciating pain. The girl accompanies him gently and teaches him to be good. The lonely boy deeply relies on her and is willing to endure the torture of the forbidden curse rather than let go. Watch how the girl uses warmth to dispel the gloom in his heart, break the forbidden curse together, and rewrite the tragic ending for both of them!
