This will be the first time the actor will be taking on a darker role, donning short cut hair and a sharp image, breaking away from his flower boy appeal.  His agency commented, "Since it was a 180-degree turn, he did feel a lot of pressure, however, he is preparing hard for his role with much excitement.  He has been practicing action sequences and continues to converse with his sunbae costars for helpful tips."

Meanwhile, 'Bad Guys 2' will air its first episode on December 16.
