Kangta mentioned prior to his friend's appearance, "It's been a very long time...The script says he's in his mid-30s but he's actually in his early 30s. We're only a year apart... He's still very much like a younger brother to me."
Lee Jae Won commented once making his entrance, "I am very happy to be able to appear on the show with Kangta hyung."
Kangta then observed, "Your voice still sounds the same," amazed. Lee Jae Won continued during his introduction, "Honestly, it's been three years since I've been on a show. I am a bit nervous since it's live and I'm worried that I might make a mistake."
He also added, "I wore sunglasses today since it was a gift from fans," making the listeners laugh.
Kangta expressed, "It's been 17 years since we've had a radio show together. The last one was back in 2000."
The nostalgia is real!
