Aon's little fanbase naturally voted for Aon, and other star's fans also voted for their own idols.
The casual audience...they looked at the judges' full satisfaction of Aon's artworks and felt that they could use their vote to help other contestants in the same group.
[His score is already high, anyway. The judge's score counts for 70%. He doesn't need our votes.]
[Who should we vote for? The one with the lowest score?]
[Eh, but I like this guy...I'll still give him my vote.]
[Then, I'll vote for the poor ones with low scores.]
Just like that, Aon had an overwhelming advantage in the judges' scores, but his vote was the lowest of the five people!
If he didn't have a nearly perfect score, Aon would have been eliminated right away.
Aon didn't know what happened outside and just waited until the program's team summoned him back into the studio.
When Aon returned to the studio, he almost slept on the floor without caring about his image.
