Is Exo’s Do Kyungsoo
His astigmatism is pretty severe, so when he’s trying to look at something from afar, he naturally makes a scary expression. There were a lot of mentions about this ever since he debutedㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ even the fans, when they debuted, they thought “huh? What’s wrong with him…?” but then with time, they realized that it was just his astigmatism. He was then known as ‘Nanshi-Kungsoo’ among the Exo members and the fans (T/N: literally astigmatic Kyungsoo).
