The female lead of this novel is called A Soft Smile. Is this a transmigration novel?

I recommend "Princess Marry: I'll Take You When I Reborn" to you. This is an ancient romance novel written by Yi Xiaowen. The main character, Guan 'er, transmigrated to the capital and became the most beautiful woman in the world. However, she had to marry a medicine pot. In the face of all kinds of difficulties and dangers, she became an extraordinary princess. I hope you like this fairy's recommendation. Muah ~😗
