She underwent a death experience—at the hands of the family she cared for most, who then sold her off. At eight years old, Seraphina Valeza was adopted from an orphanage by the Hawthorne family, a run-down third-rate family in Lunada City. She lived for fifteen years there, always careful, thankful for a house that was not her home. She was an excellent student, kept her sufferings to herself, and obeyed them in return for their "kindness." When the Hawthorne family was on the verge of bankruptcy, they chose survival over conscience. Seraphina was forced to marry Julian Moreau, the heir of a second-rate elite family.

In public, she was paraded as a trophy wife; in private, she was nothing more than a disposable tool. Once Julian seized full control of the Hawthorne family, Seraphina lost even her last value.

In real life, I had been pushed to the brink by an online romance scam. Just when everything fell apart, I awakened something called the Devotion System, and before I could make sense of it, I found myself thrown into a horror game. Among all the players, I was the weakest, barely able to take care of myself. If I wanted to survive, I had only one option—find someone stronger and cling to them, no matter what it took. However, things did not go the way I expected. Every player avoided me like the plague. Not a single one was willing to team up. With nowhere left to turn, I made a desperate decision. I chose a ghost. I treated her as my bound partner and devoted myself completely to her, clinging to her as if my life depended on it. However, as I spent more time with her, I began to realize she was not just something terrifying. She was someone who had been hurt, someone deeply broken. Hence, I stopped pretending. I began to help her sincerely. In the end, we overcame everything together and cleared the game. However, when I returned to the real world, I discovered something I never could have expected. She had followed me back. From that moment on, all I could do was wait for the system to pull me into the next stage.

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.

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.

After transmigrating into a novel, I realized the heroine and I had the exact same name. Naturally, I thought I had transmigrated into the female lead. So I marched straight to the man who was still a broke nobody at the time, threw all caution to the wind, and pounced on him like I had plot armor protecting me. He even glared at me with red eyes and told me he hated me. I honestly thought he was just into the whole push-and-pull thing. Everything shattered when the real heroine showed up and I finally understood one thing. He actually hated me. Heartbroken, I packed my bags and got ready to disappear. The next second, he pinned me against the wall. "Where are you going? Already bored of me, sweetheart?"
