Infinite Challenge
Infinite Challenge has been reported as the first "Real-Variety" show in Korean television history. The program is largely unscripted, and follows a similar format of challenge-based Reality Television programs, familiar to the audiences in the West, but the challenges are often silly, absurd, or impossible to achieve, so the program takes on the aspect of a satirical comedy variety show, rather than a more standard reality or contest program. In order to achieve its comedic purposes its 6 hosts and staff continuously proclaim, the elements of this show are the 3-Ds, Dirty, Dangerous, and Difficult.

Level Up

As head of game development at Joybuster, Shin Yeon-Hwa teams up with her new CEO, in an attempt to save their dying company. Tasked with developing a new game which satisfies all of Dan-Te’s demands, Yeon-Hwa soon finds herself wavering somewhere between having a nervous breakdown and committing murder. Completely at odds with each other, Yeon-Hwa and Dan-Te never seem to stop fighting; but everyone knows opposites always find a way to attract. Can the poker-faced boss with zero emotions and the hot-tempered game developer really find love when they can’t even agree on a way to save their dying company?
