Seo Jun Yun is an estranged man of the yakuza who cares nothing more than to get answers. Does not let you out of his sigh and never lets go. Will do whatever it takes to get what he wants. He has an aggressive temperament, enjoys barking back, and hates people with attitude and solidness. He is intimidating and strong in all capacities and even the public fears his next move, he protects those in his yakuza clan with an iron fist.
