Please recommend those good novels where the male protagonist has someone else in his heart but has no choice but to be with the female protagonist. Later, he likes the female protagonist?

I recommend 'The Nation's First Love: The Prince Charming Is Too Cold' to you. The male protagonist was cold and arrogant. He had someone else in his heart, but for various reasons, he was with the female protagonist. Later on, he slowly fell in love with the female protagonist. I believe you will like this novel. I hope you like this fairy's recommendation. Muah ~😗
