On January 15 episode of JTBC's television show 'Knowing Brothers', the members of 2AM featured as guests.
During the talk, one of the hosts Kang Ho-dong said, "Chang Min, it's been some time since I've seen you, and you've become really handsome."

Then, Jo Kwon said, "When we were getting ready to make debut, we had a video sent to us. It was said that he was the last member of 2AM; the video was of Chang Min. I was excited to finally see our last member. But as soon as I played the video, I just couldn't stop crying."
Jeong Jinwoon added, "Yeah, he's not lying. He cried for real. He cried so much as well."

He continued, "Chang Min weighed like 100 kg, and he had lots of blemishes on his face. I thought he was a college professor or something. He honestly didn't seem like a guy who would make a good K-pop star."
He resumed with a smile, "But I think Chang Min's great-looking now. Even my mom is surprised to see how handsome he looks in our album photos. She's like, 'Wow, is this really that Chang Min I know?'"
