I recommend "80's Little Doctor's Wife, She's Delicate and Flirtatious" to you. This novel also has a female protagonist who is a know-it-all who has many responsibilities. There are also plots where the male and female leads of the CEO are constantly in conflict and sparks. Although she didn't have a rich background like Xia Yiwei, the plot was very interesting and the heroine was very cute. I hope you like my recommendation. Muah ~
