Please recommend an ancient novel. The male protagonist has a cold personality and is black-bellied. He slowly falls in love with the female protagonist.

I'm picky about reading articles and often have a shortage of books. I hope my friends can recommend some good articles!
The detailed requirements were as follows:
1. The writing style must be good. One on one, the male and female protagonists must be single-minded. It's best if the relationship is slow and gradual. It's best if the ending is He.
"2. Ancient romance, ancient martial arts, Xianxia fantasy, ancient time travel. There is no limit to the genre. The plot cannot be too tacky. It is best to avoid harem novels. I am tired of reading them."
3. The female protagonist doesn't need to be omnipotent and powerful. It's best if she's natural and ordinary, smart and open-minded, not fickle and not infatuated.
I recommend a few of my favorite masterpieces:
Nirvana in Fire, a classic in ancient novels
The plot of " Long Running Water " was very much liked by the male and female leads. The ending was a little tragic.
Wandering Youth was the favorite Wuxia novel in ancient times.
The male lead of Moon in the Sky was unmoved, but his emotions looked very warm and delicate.
" Meeting You Again in the Falling Flower Season,"" Aquilaria Fragments,"" The Flower of Qiyuan, Thousand Bones of Xianxia," were his favorite works in Xianxia fantasy novels.
The male leads of " Su Ji Coffin Shop " and " Shuang Que " were all cold and reserved.
If you haven't read the above, don't miss it. Good articles should be shared together. I hope everyone can recommend it!
Please give a brief introduction of the content or the characters! Thank you!

Answer 1

I'll Live to a Hundred Years After Hugging the Villain State Preceptor. This book might meet your needs. The male protagonist was weak and sickly, cold and indifferent. When he first came into contact with the female protagonist, he did not have any love for her. However, during the process of contact, he gradually developed feelings for the female protagonist and finally doted on the female protagonist. The female lead was also a woman with her own thoughts. The interaction between her and the male lead was full of sparks. I hope you like my recommendation. Muah ~
