In the upcoming episode of “Running Man,” the Big Bang members came on as guests. During the filming, TOP showed a very unexpected and new side of him. In KBS drama “IRIS,” TOP played a charismatic killer, but here, he showed his clumsy side. Taeyang commented on the transformation, “Unlike people’s image of TOP, he is the Gwang Soo hyung of Big Bang. He is not cold, but rather he is a soon-doong-ee. In other words, he has his clumsy side.” Soon-doong-ee is a nickname to describe sensitive and clumsy people. Read more on Allkpop.
