The Arrogant Black-Bellied Prince

She was a modern mercenary who relied on her formidable abilities and always worked alone. She moved freely between the underworld and the legitimate world, inspiring fear with her reputation and making others think twice before challenging her strength. One day, she inexplicably transmigrates and becomes the daughter of a military family in another kingdom. After an accident leaves her blind, her life is swallowed by endless darkness. People say she is cold and unpredictable, and cruelly harsh with her servants. Her reputation as a vicious woman resounds across the land, but no one knows what brilliance lies hidden beneath the surface... He is a prince from a neighboring kingdom, rumored to be a womanizer whose greatest pleasure is spending his days in the pleasure quarters and teasing beautiful women. His reputation as a flirt is on a par with hers as a poison woman, but no one knows how many people will surrender without a fight when the mask of the playboy is lifted, willingly bowing to him... She is the King of Ghost Valley, feared by both sides of the martial world. Cold and bloodthirsty, she uses cruel methods against her enemies. Though young, her strength is not to be underestimated, and few in the martial world can match her... He is the master of the Hidden Star Pavilion, as cunning as a fox and so unpredictable that no one can read him. He cares nothing for right or wrong and does only as he pleases. His power runs deep... She is a military strategist who commands the battlefield and plans for victory. Only a promise brought her to war: she uses her abilities to help one person protect a territory, but never intended to use them to expand her own country's borders. She has no desire for war, yet cannot simply stand aside... He is a hidden power broker who issues commands as if he were on the battlefield himself, controlling the whole situation. To him, the battlefield is no more than a game of chess, a diversion to relieve his boredom. When an opponent of equal ability suddenly appears among the enemy forces, the battlefield finally gives him the entertainment he craves... She is... He is... Two people of equal strength... two equally brilliant and gifted people... two people with many identities... two people of ever-changing temperaments... They clash again and again from the shadows, evenly matched and unable to defeat each other. Neither knows the other's true identity. They regard one another as worthy opponents, but nothing more... They should have had nothing to do with each other in real life, but after an unexpected encounter, a written contract entwines their fates. Pursuing their own goals, they join forces to create one thrilling, unforgettable chapter after another, leaving a lasting mark on history... But once everything is settled and the contract they agreed upon comes to an end, she appears to leave without a backward glance, as promised. Why, then, can't he forget her? Why has he begun to entertain the naive hope that the contract might never end? (I'm no good at writing synopses. If you enjoy the story, please support it by adding it to your favorites. Thank you!)
