Lee Joon took off his shirt during filming.
In the episode aired on the afternoon of the 15th, the members of the KBS2 variety show '1 Night 2 Days Season 4' (hereinafter '1 Night 2 Days') were seen spending their free time in different ways.
In this broadcast, Jo Se-ho and Lee Joon seemed to have come to the gym and started exercising. When Jo Se-ho unbuttoned his vest, Lee Joon said, "If you're going to do that, wouldn't it be better to just take it off?" and took off his shirt.
Showing off his angry muscles, he volunteered to be Jo Se-ho's personal trainer for the day, and the two filled their free time with exercise.
Jo Se-ho, who also took off his shirt, made a face realizing the situation and laughed, saying, "What is this?"
'1 Night 2 Days Season 4' can be seen every Sunday at 6:10 PM on KBS2.
