After the male protagonist discovered the female protagonist, he trained her to be an assassin or an agent. Did they fall in love in the end?

😋I recommend the following two novels to you: 1. "My All-rounded Medical Concubine is Super Fierce." The male protagonist was reborn, and the female protagonist transmigrated. She had special agent skills. Although it's not a modern language, it suits your needs very well. The female protagonist has also become a secret agent. The relationship between the protagonists also developed slowly. 2. In "After Rebirth, She Became a System", the female protagonist was sucked into the game when she was playing a game adapted from a novel. She suddenly became the system of the female protagonist's cheat, but after interacting with the male protagonist, she became the female protagonist. The male protagonist was also a well-trained agent, but he did not directly train the female protagonist. The relationship between the protagonists also developed slowly. I hope you like this fairy's recommendation. Muah ~😗
