Visuals are definitely an important aspect of fully portraying a role, and actor So Ji Sub made sure he perfectly fits the part of the cold yet charismatic boss he plays by making sure not a single strand of hair is ever out of place!

'The Sun of My Master' hilariously compiled a set of behind-the-scenes photos of So Ji Sub looking at the mirror every time he gets a chance. Although you may think it's narcissism, they reveal that the actor is not just checking himself out, he's observing his own expressions to perfectly carry out his role once the camera starts to roll.
