😋I recommend "Evil Princess Not to Be Trifled With" to you. Although the protagonist of the novel is not A Soft Smile, some of the plot is similar to the information you provided. It is also a female protagonist who is brought to ancient times. She has a stubborn personality and is full of courage. She specializes in causing trouble and changing her fate. She had also sold herself before, but after being bought by another male lead, she slowly fell in love with him and became a pair of enemies. I hope you like this fairy's recommendation. Muah ~😗
