While it's not as common in Korean webtoons, in Chinese webnovels this is a usual trope: "villains being petty mediocre people who scheme to frame and bring down a talented protagonist, out of sheer envy and their own inferiority complex." This is such a prevalent, used and abused theme, they even have the label of "cannon-fodder villain" exclusively for these types of "pathetically-motivated" villains. They're so recurring, that I wouldn't be surprised if it turns out they had started spreading to the fiction made in other countries.
