SIMILAR to Vnet's previous hit show, Idol Producer, the contestants' rankings in Boys Odyssey were determined by public voting. However, unlike Idol Producer, where only the Korean audience could participate, Boys Odyssey expanded its voting system to include international viewers. Throughout the competition, voting was split evenly, with 50% of the votes coming from domestic audiences and the other 50% from global fans.
Due to the rigging scandal that led Vnet to discontinue the Idol Producer series, Boys Odyssey ensured that the voting process was completely transparent and free from manipulation. As a result, the show's PD in Haneul's previous world, responded to this stricter oversight by resorting to using "evil editing" tactics to diminish the chances of contestants he didn't favor. However, this also meant that those who ultimately debuted did so purely based on their genuine popularity with the audience.
This was especially evident in the case of Han Seojun.
