In this novel, the male protagonist was called " Big Brother " by the female protagonist?

"I recommend General, Be Kind." This is an ancient romance novel. As soon as the female protagonist transmigrated, she met the little male protagonist at the human trafficker's place and said,"Let's be together forever," as if she was coaxing a child. The male protagonist chased the female protagonist, lied about his age, and became the female protagonist's "big brother." He made the female protagonist step by step into the male protagonist's house. The female protagonist thought that she was escaping from the marriage, but it turned into a gift. The escape along the way turned into sweet dates. This was the story of a black-bellied male protagonist wooing his wife. In order to get the female protagonist, he meticulously weaved a 360-degree net with no blind spots for her, just to firmly trap her and fulfill his promise of "Let's be together forever." I hope you like this fairy's recommendation. Muah ~😗
