😋I recommend you an ancient novel,"The Female Supporting Character is Extremely Handsome". Although it doesn't completely match the plot information you gave, it also has a similar plot setting. The female protagonist, Bai Yixi, bullied the male protagonist when she was young, but when she grew up, she found out that the male protagonist was her first love."What Bad Intentions Can the Female Lead Have" also has a similar misunderstanding and reconciliation between the female protagonist and the male protagonist. This novel was also recommended by the editor recently. It was very interesting. I hope you will like it, muah ~
