I'll recommend two books that I read a long time ago. The first one is about transmigration. The female protagonist traveled to ancient times and met the male protagonist on the mountain. The male protagonist is the emperor. I remember that the male protagonist once made a promise.

The first of the two books that I read a long time ago was about time travel. The female protagonist dressed in ancient times and met the male protagonist in the mountains. The male protagonist was the emperor. She remembered that the male protagonist had promised to only have the female protagonist alone, but in the end, he didn't. Later, one of the concubines became pregnant and was discovered by the female protagonist. The female protagonist was very sad, as if she was struck by lightning in a temple and returned to the modern world.
The second book was a hardcore one. The male protagonist was a playboy, and the female protagonist seemed to have resigned to work as a real estate agent with the second male protagonist. Moreover, the male protagonist and the supporting male protagonist had slept with the female protagonist. The most hardcore one was that the male protagonist and the supporting male protagonist had also slept together. The ending seemed to be that the male protagonist could not change his playboy character, and the female protagonist left them. It seemed that the second male protagonist had gone after them.
Please tell me the title of the book. Thank you.

Answer 1

Book recommendations:
1. "The Light of Tongxi": A novel of transmigration. The female protagonist has two identities and walks on the edge of two beliefs. She is trapped between betrayal and loyalty. She faces the love mystery of two hostile men. It is recommended with deep feelings.
2. "Dear Concubine: Emperor, Take It Easy": A novel about a fight in the palace. The female protagonist disguises herself as a man and rides a horse with a knife just to find out the truth. She and the male protagonist dislike each other. It's sweet and not cruel. It's highly recommended.
I hope you like my recommendation. Muah ~
