Webtoon writer Jung Eun-Ha is serializing romance novel with the lowest rating. Eun-Ha picks up a pencil with his desire to draw a popular webtoon and wakes up in his own webtoon. It's been said that they've been in the webtoon before, and they've all been ripped out and put on the top of the popularity rankings... Then, the first thing to do... is to kill the male lead so that romance doesn't happen?! *“From today on, this webtoon will change its genre to school violence!!”* (Source: Naver, translated)
