I recommend "Get Dressed Quickly and the Female Supporting Character Is Extremely Fierce". The plot of this novel is similar to "First Love's Counterattack System". Both of them are about the female protagonist changing her identity due to the appearance of the system, and in various plots, she will counterattack and abuse the scumbag. At the same time, this novel was also a fast-moving story with the setting of time-travel. I hope you like my recommendation. Muah ~
