Sinan, the cold-blooded female CEO of Hong Kong City who has experienced ups and downs, took a serious look at his friend Jiang Yi for the first time at his brother Si Yan's birthday party - a sunny and handsome medical genius, but his eyes seemed to hide whirlpools. In the tense life of family strife and old enemies, she became playful and dropped the bait that seemed to be nothing. Jiang Yi bites the hook seemingly innocently, but turns into a considerate "naughty dog", making soup for her to sober up, solving business difficulties, and even blocking a fatal knife for her. Si Nan enjoyed the feeling of control, but he didn't know that Jiang Yi had already spun a web. When Si Nan was abducted by the culprit of the kidnapping case, and his life was hanging by a thread, Jiang Yi tore up his disguise, revealed his hidden identity, crushed the enemy with thunderous means, and locked her bruised body into his arms. His voice was hoarse: "Sister, what you caught was never a docile puppy. Now, it's my turn to 'serve' you." Who will decide the outcome of this heart-hunting game that begins with control?
