They covered half of their eyes.
We found out the meaning of this gesture through Lotte Duty Free report from Song Seung Hoon’s filming of his Lotte ad where he was also ordered to have a pose of covering half of his eyes with one hand.
Then.. what does the gesture mean?
In Korean there’s a saying “don’t sell half your eye”. This means “don’t look at others” (believe in yourself).
