I recommend "Five Years After Escaping From Marriage, I Caught My Child And Ran Into The Prince's Arms" to you. This book is an ancient romance novel written by the author, Song Yiqin. The female protagonist was a concubine's daughter who was not liked in the Cheng Mansion. She was given a marriage to the Regent King, but she ran away from the marriage twice. The male protagonist was the sickly regent and the younger brother of the Emperor of Tianxia Country. Xiao Tuanzi, who looked exactly like the female protagonist, was sent to the entrance of the Prince's mansion. It turned out to be her son. The two of them didn't like each other at first, but after a lot of melodramatic things happened, they finally fell in love. I hope you like this fairy's recommendation. Muah ~😗
