Every year, around 1,100 thousand couples in South Korea filed for divorce, so it is common to see or know some divorcees in every social status. But, there is one specific group of couples that haven't get a divorce yet: the comedian-comedienne couples. Can't Be the First is a reality show featuring three comedian-comedienne couples who do their best not to be the first divorced comedian couple. Viewers can watch their daily lives filled with boisterousness, anxiety, happiness, and agony. Moreover, Park Mi-sun joins as one of the hosts and empathizes with the couples' situations and feelings since she also married to a fellow comedian.
