The Yandere Beauty's Possessiveness Is Too Much to Bear

After waking up from a coma, Du Bei finds himself locked in a dark basement, covered in wounds. The woman before him, Su Xianning—his classmate since middle school who always competed with him for first place—is calmly applying makeup in front of a mirror. She loves him. In a twisted, extreme way. The basement is filled with torture instruments, each with a name: 'Green Snake,' 'Candle Bone'... Su Xianning demonstrates the force of a whip and the skill of a dagger, her tone gentle as if introducing a new home. She cries and begs him to 'be good,' but when he refuses, she lashes him with the whip. Every strike precisely avoids vital spots—she is in control, which is more terrifying than the pain. When Du Bei's blood pools and his consciousness fades, Su Xianning breaks down. She kneels on the ground, trembling, crying, 'This isn't what I wanted.' She unties him from the cross, holds him in her arms, changes his bandages, applies medicine, brings down his fever, and stays by his bedside all night. The door is left ajar. She leans against it outside, crying silently. Is this love or imprisonment? Du Bei doesn't know. He only remembers the question from his fever: after taking the medicine, what is he to her?
