# Problematic Men

Problematic Men (Korean: 문제적남자) was a South Korean television program that aired on tvN. It starred Jun Hyun-moo, Kim Ji-seok, Lee Jang-won [ko] (Peppertones), Ha Seok-jin, Joo Woo-jae and DDotty.
The program went on hiatus after its broadcast on March 25, 2018. On May 9, 2018, it was announced that the program would be returning as Season 2 from May 29, and would air on every Tuesday at 23:00 (KST), with no change in the current cast lineup. Beginning January 7, 2019 the program aired on Mondays at 23:00 (KST).
The program was on another hiatus after its broadcast on June 10, 2019, as the program was to be replaced by More Salty Tour in its time slot, and it was slated to return in the second half of 2019. On October 28, 2019, tvN confirmed the program would return as Season 3 starting November 21, 2019, with original cast members Tyler Rasch and Park Kyung (Block B) not returning. Plus, model Joo Woo-jae and YouTuber/entrepreneur DDotty [ko] would join the cast as new members.
The program had an indefinite hiatus as of February 13, 2020, due to the COVID-19 pandemic in South Korea, which made filming of the program difficult. No update about the show was announced, indicating that the series has ended.

## Program

It is a talk show variety program that focuses on various types of problems every week, sometimes with a theme. The cast invited for this program are 6 males, that have been labelled as "men with hot brains".
Traditionally, the cast is given clues to guess the identity of the episode's guest(s), and once the guest appears and are introduced, they and the cast are given a set of problems to solve. It is a tradition that all problems for the episode must be solved before the whole recording of the episode would end.
Season 3 features the theme of Brain Wanderers Squad/Travelling Brainiacs (Korean: 브레인 유랑단), where the cast goes outdoors, unlike most of the previous 2 seasons when they were in the studio. The 6 cast members travel to various places around South Korea, varying from campuses to companies. For each place, the members would be split into 2 teams of 3 to look for people who they think are hidden brainiacs in the place and each team selects one to join, and the 2 teams go against each other in a battle of problem solving. The winning team can get off work on time, while the losing team has to stay in the campus to study after filming for the show is complete.
