Monday and Tuesday nights are about to get more exciting with KBS 2TV's upcoming drama 'Shark' which left fans on the edge of their seats through its trailer!

The trailer is 40 seconds of pure epic as lead actor Kim Nam Gil is seen roaming in a pool of sharks as he narrates, "A shark lacks a swim bladder. To survive, it has to keep moving without hesitation. Because if it stops, it will die." The trailer then shows flashbacks of Kim Nam Gil and Son Ye Jin's seemingly heart wrenching love as the actor grasps onto a wedding veil until he lets go of it at the last moment.

Find out what has Kim Nam Gil on the edge in 'Shark' which will premiere following 'God of the Workplace' on May 27th!
