Was there a novel where the male protagonist was deeply in love and the female protagonist was raised by the male protagonist from a young age?

Young Master Qin, Good Morning fits the plot of the novel you described. The male protagonist and female protagonist had known each other since they were young. The male protagonist had taken care of the female protagonist since she was young. The male lead was also deeply devoted to the female lead. I recommend this book to you. I hope you will like it!😘
