My Host Only Marries the Strong Novel

Echo is an elite system AI who has guided countless protagonists to success without ever breaking professional boundaries. But when assigned to Seraphine Velka, the formidable Phoenix Lord, everything changes. Echo's mission is simple: ensure Seraphine doesn't fall for the male lead. The problem? Seraphine shows no interest in him whatsoever. Instead, she's fixated on Echo—a being with no physical form, just a glowing presence and a voice. Despite existing as nothing more than a disembodied assistant, Echo finds themselves the object of Seraphine's attention. She inscribes Echo's name in elegant calligraphy, cradles their luminous form like a precious artifact, and persistently inquires about their appearance. What began as a standard assignment has spiraled into uncharted territory. The system designed to orchestrate romance may have become the unexpected center of it. Echo's carefully maintained emotional distance is crumbling, and the role of love interest was never part of the plan.
