There were quite a few novels of this type, such as "President Gu, Your Character Setting Has Fallen Again","The Survival Manual of the Di Daughter","Her Young Master Pei Is Mr. Three Good", and so on. They were all plots where the female protagonist was reborn and returned to a few years ago. However, the one that met the requirements the most was "Sweet and Sweet First Love." The female lead was reborn back to the school days a few years ago and started her first love again. I hope you like my recommendation. Muah ~
