Kim Bum has been making waves with his new look for his upcoming series Hidden Identity. Not only did the actor lose 14 kg (31 lb) for the role, but he also cut his hair shorter than it has been in years! In this behind-the-scenes footage from the Hidden Identity poster shoot, you can watch as Kim Bum loses his locks and see his cute reaction.

What do you think of his new look? Kim Bum can pull off pretty much any look, and the shorter style certainly seems to match his gruff character.

Hidden Identity will premiere exclusively on DramaFever on June 16. Receive new episode alerts by becoming a fan of the series HERE, and check out the latest trailer below!
