SHINee's Key shares a group photo taken with musical 'Chess' team 2AM JoKwon, B1A4 CNU, VIXX Ken and other cast.

The photo is taken from their musical rehearsal so it's reasonably that all of them look exhausted. The idols are very passionate and hardworking ever since they've begun practicing in order to show their best performance.

Although exhausted, the four look happy and smile for the camera. Meanwhile, musical 'Chess' performances will kick off from June 19 until July 19 at Sejong Grand Theater.
