I found this series through random viral Tik Tok posts? Read all of the Webtoon Chapters as it appears to be a 3/5 star series. The female MC is a self established strongest in a school for the bottom pit of youths. She carries strength and wits of a delinquent of sorts but chooses to live for herself. It is only until her favorite childhood teacher enrolls in her school till she decides to renovate the institution. Story wise it's okay but not the best setting I have seen in these kinds of stories. Her idea of force converting the school to become good by strength alone issilly. It doesn't help the main male teacher has no strength to back up his kind resolve.
