>>93149031I dunno about their TV but I've been addicted to Korean webtoons for years and literally all of them feature revenge as a major subplot, if not the main plot, no matter the genre or tone of the work. The worst are the villainess ones because most of them seem to want to condemn anyone whoever slighted them in the smallest way, even for perfectly understandable reasons, to some fate worse than death.
Kinda gave me an image of Koreans as the most vindictive petty people on earth.
