I recommend " The Ugly Daughter-in-law: The Beloved Wife of a Han in the Mountains " to you. Although the female protagonist is not the daughter of the richest man, the male protagonist is also a rich family's son. When the female protagonist first transmigrated to ancient times, the male protagonist saved her. Later, due to some misunderstandings, the female protagonist almost became a monk. This book was very interesting. The female protagonist was a concubine's daughter who wanted to change her life and live a well-off life. The male protagonist was a rich young master with a petite figure and exquisite facial features. The couple's love line was very sweet. I hope you like this book.😘
