Can you recommend some ancient romance novels where the male protagonist is strong and cold, but only gentle to the female protagonist?

I recommend the novel,'The Prime Minister's Uninvited: Madam, Too Vicious Tongue', to you. The male protagonist was a powerful man, but at the same time, he had a hidden teasing attribute. The female protagonist looked cold on the outside, but she was secretly coquettish and occasionally had a poisonous tongue. The male protagonist was only gentle to the female protagonist, and the relationship between the two was also very exciting. I hope you like this fairy's recommendation. Muah ~😗
