Three years ago, Hazel, a human girl with a background in espionage, secretly donated her kidney to her werewolf boyfriend, Kael, who was critically poisoned. Unbeknownst to him, she betrayed him with his antagonistic half-brother, Silas, and then went to another city to recuperate. Three years later, Hazel's health deteriorated due to rejection, and she returned to her hometown to fulfill her long-cherished wish of "seeing him again," working as a receptionist at the hotel Kael had booked. The two met again, and Kael hated her intensely, subjecting her to countless humiliations. Only when Silas released the surgical records did Kael learn the truth. Filled with remorse, he rushed to the operating table, praying that she would survive and start anew.
