Was there an older novel where the female protagonist was not beautiful but intelligent and indifferent?

The female protagonist seemed to have found the male protagonist to pay off her father's or family's debts. The male protagonist's family had an underworld background. The male protagonist wanted the female protagonist to be a shield for a woman he had a good impression of. As they spent more time together, the male and female leads gradually became attracted to each other and fell in love with the female lead. However, it seemed that the male protagonist did something that hurt the female protagonist. The female protagonist fled to a relatively simple village and even gave birth to a child. The male protagonist couldn't stand the days without the female protagonist and went to look for her. The female protagonist didn't forgive him, so he protected the female protagonist and the child until He. This is a novel I read a long time ago. The plot might be a little different from what I described. I forgot the name after a long time.

Answer 1

The book "Immortal's Indifference" fits your description. It's a fantasy romance novel written by the author Yue Lao. After the female protagonist is reborn, she recovers her missing memory fragments and is "favored" by a tsundere immortal. She then embarks on a path of no return. The female lead looks ordinary, but she's smart and indifferent. She fits the characteristics you described. I'm recommending it to you. I hope you like this fairy's recommendation. Muah ~
