On one side, there is Kangin.

There, that is Yesung.

And here come Heechul and Leeteuk.

The P.A. had commanded them to head to the center chamber.

A series of green arrows on the walls would show the way.

Kangin, rage flashing in his eyes.

Yesung, determination powering him.

Leeteuk, resignation shown in every move.

Heechul, ranges of emotions on his face.

Where only one may survive.

The Final Decision.
