On the March 1 airing of tvN's 'Life Bar', the MCs asked Kim Jae Wook, "We heard you really worked part-time at a transgender bar?"
Kim Jae Wook answered, "I made a visit to check things out but I felt like I needed to learn a lot more if I want to prepare well [for my transgender role]. So I asked permission from the boss and worked for a short while without pay."

He added, "It helped a lot. Nobody noticed me."
Sounds like a cool experience!
