At seventeen, love feels infinite and endings feel impossible. Arielle never planned to fall in love during her final year of high school. Noah never planned to let his guard down. But when quiet glances turn into late conversations and unspoken feelings surface, they find themselves caught in a connection neither of them is ready to name or walk away from. Set against the fragile edge of senior year, Promises We Made at Seventeen is a slow-burn, dual-POV romance about first love, fear, and the weight of choices made too young to fully understand, yet too deep to ignore. As expectations, rumors, and the future press in, Arielle and Noah must decide whether honesty is worth the risk and whether promises made before adulthood can survive what comes after. Tender, dramatic, and emotionally raw, this story explores what it means to love someone while still learning who you are, and how some promises no matter how small can change the course of a lifetime.

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.

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.
