This apparently took place yesterday (19th KST) and one of the cast members, actor Choi Min Soo, and one of the PDs of the show got into a physical altercation. Heated over differing views on the filming concept, the two started to push and shove and Choi Min Soo ended up throwing a punch at the PD's chin. The PD was taken to the hospital to get treated.

With word spreading about this, the staff of 'A Look At Myself' revealed that Choi Min Soo personally apologized later. On the 20th, the show stated, "Choi Min Soo came to visit the PD in person and apologize first. As this happened because the two were so passionate about the program, the PD himself also talked out the matter with him to resolve their misunderstanding." 

The staff also emphasized that the actor will not be leaving this program due to this, which means he'll continue to play the part of Hongki's 'manager' on the variety show.
