[A bright, alluring, bold, and fiery seductress VS a tough, abstinent police captain] Lu Chenyuan, the captain of the Seoul police force, is known in the industry as the "Crazy King of Hell"—a towering 195cm figure with hard, muscular muscles, ruthless and decisive in his actions, harboring an extreme possessiveness, and the word "heartbeat" is completely foreign to him. Until the alluring Su Wan crashes into his world, relentlessly pursuing him with a desperate courage: "Lu Chenyuan, I want you to be my first man, and my last." Like an inextinguishable flame, she ignores his cold rejection, barging into his office in a red dress, feeding him sweet cake, singing songs of unrequited love in a bar, and then dancing a carefree dance in front of him to declare her surrender. At first, he loathed her clinginess and rebuked her recklessness, yet he felt a pang of unease when she crouched by the roadside crying, flew into a rage when people talked about her, and lost control when she resolutely turned away… “Su Wan, you want to escape?” He handcuffed her wrists, his eyes burning with an obsessive and deep affection. “You provoked me first. Even if you run to the ends of the earth, I will bring you back and lock you by my side for life.” A tug-of-war of “she escapes, he chases,” a forbidden entanglement of “forced possession + extreme pampering.” When the obsessive nature of a celibate detective meets the tenacity of a seductive temptress, whoever falls in love first loses completely—and he, he revels in it.
