Jooin is een 17-jarige studente die in de war is door de liefde. Ze veroorzaakt chaos met een paar woorden die zij in een vlaag van woede uitspreekt. Er komen anonieme briefjes binnen waarin haar daden in twijfel worden getrokken, waardoor haar rustige leven verandert.
Nee, helaas is 세계의 주인 nog niet beschikbaar op Netflix in Nederland.
