Ami, a top medical PhD, is calm and rational, devoting herself wholeheartedly to medicine. To resolve her family’s crisis, she agrees to a two-year contract marriage with Lorcan. She thinks this marriage is merely a cold transaction — a marriage certificate, mutual non-interference, and an amicable separation when the term ends. She never imagined the contract she signed would awaken a dormant beast. Lorcan, the Third Young Master who wields power over both the legitimate and underworld spheres, is wild, ruthless and aloof. He harbors an almost morbid aversion to women and never allows anyone to get close to him. Only when it comes to Ami does he close in step by step, determined to possess her. In the heat of an argument, he holds her fast, his tone shameless and domineering: “We are legally married. It is only right that I have you.” Before the two-year contract expires, he has torn up every clause of their agreement. His intense, obsessive love surges forth, threatening to engulf her completely. Overwhelmed by suffocation, the brilliant doctor chooses to run away. Thus begins the chase: she flees, and he pursues relentlessly. Everyone knows Lorcan is untamable and cold. Few realize all his indulgence, extreme favor and wild devotion belong solely to Ami. The world believes this is nothing more than a temporary deal. Only Lorcan understands — he has never wanted just two years. He wants her, for the rest of his life.
