Was this novel about the male protagonist's father adopting the female protagonist?

I recommend "Separated by a Wall: Addicted to Addiction by a Male God." The male and female protagonists are both physically and mentally healthy without bad habits. The male protagonist saved the female protagonist and was adopted by the female protagonist's father. The male protagonist doted on the female protagonist very much. From being young and ignorant to being young and frivolous to being mature and steady now, he had always been the same to the female protagonist. I hope you like this fairy's recommendation. Muah ~😗
