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.

The day my elder sister stole my fiancé from me, I did not fight back. Instead, I slipped past the maid guarding me and went straight to find my father. “She can have my fiancé. I’m marrying the Regent!” My father stared at me in shock. Everyone knew the Regent was in charge, but rumors said he could not father a child and had a nasty temper. What they did not know was that I was born under heaven’s favor—blessed with the gift of life itself. In my previous life, that blessing became my curse. My elder sister and stepmother smeared my name, claiming that my curves and easy fortune meant I had been defiled before marriage. My fiancé was disgusted and turned away from me. That was when my sister seized the chance to take my place. Even on her wedding day, my sister was not at ease. She had me dragged away like a lowly servant and sent to a brothel, ordering the madam to torture me. While I lay dying in the dark, she lived in the light, bearing children with my former fiancé and enjoying a lifetime of happiness that should have been mine. Now that I had been given another life, I refused to bow to fate again. She might have stolen my fiancé, but she could never take the blessing I was born with.

In Reychelle City, a contest was held to crown the most beautiful woman. After my cousin scarred my face, she seized first place with ease. What she never expected was that this year's contest wasn't for fame; it was to select the future wife of the Third Prince, a ruthless, bloodthirsty eunuch. That very afternoon, gifts poured in by the cartload. My betrothed panicked. That night, he tore up our engagement contract and carried my cousin into the bridal chamber. The next day, she trailed her lacquered fingertips across my cheek and sneered, "Alicia, with your ruined face, who would ever want you? Perhaps the beggar at the street corner might take you in." I caught her wrist, let out a cold laugh, and said, "Who told you I would marry a beggar?" Before her stunned eyes, I pushed open my parents' chamber doors. "Mom, since Maggie doesn't wish to be the prince's consort… let me take her place." Three years later, before the eyes of a shocked court, the Third Prince entered the grand hall with me at his side, with two children in tow. No one had foreseen it. This body of mine, blessed with the rarest gift of fertility, was the perfect match for a man believed incapable of siring heirs.

There was a river that ran through our village. According to the legend, a river god dwelled in its depths, and every month on the 15th, the village had to send a young woman to enter the water and serve him. At first, everything seemed normal. After their service to the river god, the women would return to shore, go home, and eventually marry and start families. But this year, the peace was shattered. Every woman who spent the night with the river god turned up dead, their naked bodies floating to the surface. I secretly watched as they retrieved the corpses twice. The evidence of the violation was horrific. This month, I was selected. I had been chosen to marry the river god.

In my previous life, my parents doted on my frail, sickly younger sister. For her sake, they chose a hawk beastman willing to settle in a human city as her husband. Me? They cast me into the deep sea, marrying me off to a giant shark beastman. When the apocalypse came and torrential rains drowned every human city, my parents and sister were left clinging to a rotting plank, adrift on the endless ocean. I couldn't bear to watch them die. With my giant shark husband, I dragged them down into the deep sea to safety. But resentment festered. Seeing me live comfortably while my shark beastman hunted day after day, my parents grew furious that my sister's life paled in comparison to mine. In their jealousy, they laced the fish we ate with poison and killed me. Now, given another chance at life, they've decided my sister should marry the giant shark beastman instead. My biased parents believe she will finally enjoy the blessings they once denied her. But what they don't know is this: after the cataclysm, fish become scarce. And a giant shark… does not survive on scraps. He needs flesh.
