On the March 30 episode of 'New Yang Nam Show', BamBam shared about the first time he met Youngjae, and said, "I was only wearing my underwear at our dorm because I was about to take a shower. But then I heard someone trying to open the door and I wanted to surprise the hyungs so I took off my underwear and just stood in front of the door. But a new JYP trainee Youngjae came in..."
Youngjae commented that he was very shocked and didn't know how to react.
BamBam continued to explain, "I was so shocked. I had to put my underwear back on but I ended up just bowing (in greeting) with my hands up in the air."
