Shi-Woon Yi

Shi-Woon looks much like any other Korean high school student, often dressing in his uniform and later on in sweat suits. He has shaggy hair and an unremarkable "failing" face. His body is particularly skinny with little to no muscle at the beginning of the series, as made evident by his inability to complete most basic physical exercises, which may be due to his particular body condition, resulting in a body that was naturally inferior since birth. Although his strength has increased after receiving training from Han Chun-Woo, his body didn't change much; however, his fashion sense looks to be getting more and more like that of Hyuk So-Chun . Recently his body has became more muscular comparable to other Murim like Han Chun-Woo or Kang Ha-Il.
