I Am the Commander of the Second Male Lead's Knights

After a devastating monster attack claims the lives of her family, Nina is sold into servitude at House Louvoirennais. There, she encounters Adrian, the tragic second male lead whose future holds nothing but abuse, betrayal, and an untimely death. Refusing to let his grim fate unfold, Nina resolves to rewrite his story by becoming both his closest friend and fiercest protector. Her singular goal is simple: keep him alive and shield him from the cruel destiny that awaits him. As Nina dedicates herself to this mission, she steadily climbs the ranks of the elite Black Knights, transforming from a vulnerable servant into a formidable warrior. However, her carefully laid plans take an unexpected turn when she accidentally summons Sol, a remarkably powerful elemental. This unforeseen event shatters the boundaries of her original intentions, revealing that her role in this world extends far beyond safeguarding one doomed young man. Bound to forces greater than she ever imagined, Nina realizes that saving Adrian might only be the beginning—and that her true destiny may demand nothing less than saving the entire world.
