Actor Kang Ha Neul revealed why he went into theater immediately after 'Misaeng' at a time when he was super busy in the January issue of performing arts magazine, 'Scene Playbill.'

He said, "When I said I was going to be in a play when I was at my busiest, there were a lot of people around me who asked if I were crazy.  However, something intense grasped my heart when my thirst for learning was great and brought me to personally start learning again.  That was theater."
