There were a few novels that could be recommended, including " The Road of a Useless Girl's Counterattack,"" Love Confession Practice,"" The Life of a Small Official in the Ming Dynasty,"" A Farmer's Wife Is Not to Be Trifled With, Abducting a Husband to Earn an Imperial Mandate,"" East Bed," and " The Group's Favorite Fuwa: Little Milk Bun Is Milk and Fierce," etc. These novels might be related to the female lead, but the specific plot and content needed further reading to confirm.
An Xiaoyu and Tao Zhixiang were not characters in a novel but two characters in a fictional story. This story was often called " The Cute Wife of a Bestie " or " The Cute Husband Asks for a Hug ". It was about the love story between An Xiaoyu and Tao Zhixiang.
It could be a random character created for a pulp - fiction - style story. Maybe a detective's sidekick who got caught up in a dangerous case and unfortunately died.
