Born with angelic blood, Lixue has lived her entire life bound to a prophecy she never chose. Raised in the countryside among a family who shared her celestial heritage, she was sent to Heaven at the age of seven to serve the Father and awaken the powers hidden within her soul. But a single night of tragedy shattered her peaceful life—demons invaded their ancestral mansion, and in the battle that followed, Lixue lost both her mother and her brother. From that moment on, her heart closed itself to the mortal world. Haunted by loss and unable to accept death, Lixue disappears into the Philippines, working as a secret agent for her godfather’s underground organization. Her latest mission seems simple: protect Shuji Liao, a world-renowned model, from an unknown stalker. To stay close, she hides her true identity and lives under the same roof as Shuji and his father. But as Lixue investigates, she uncovers a far darker truth—Shuji’s family is entangled in a powerful criminal syndicate that threatens both the mortal and supernatural realms. Shuji, raised between two countries and burdened by a fractured family, finds his once-stable life unraveling. A mysterious incident alters his heart, pulling him away from his girlfriend and toward the woman sworn only to protect him. What begins as duty slowly turns into forbidden love. Unbeknownst to Shuji, a single kiss seals their fate. The prophecy awakens, revealing its cruel demand: Lixue must love Shuji and bear a child destined to save the world from demons, devils, and ancient evils that walk the Earth. But salvation always comes at a price. After their child is born, Lixue vanishes—erased like a dream at dawn—leaving behind a son, a broken lover, and a world saved by a sacrifice no one will ever forget.
