He is the director of Sunjin Trading, a Castle-affiliated company, and Baek Do-chan 's right-hand man, and one of Castle's Top 10. Considering that he calls Shin Tae-jin his senior, his career itself seems to be shorter than Shin Tae-jin.
He is from a conflict zone in Southeast Asia and is the barista 's sworn brother. He entered the criminal world after meeting Baek Do-chan, who was on a mission in the past, and was later recruited by Baek Do-chan, whom he reunited with, and became a member of Advanced Trading.
