Veteran singer Yoon Jong Shin recently revealed his affections for junior group Super Junior, who just unleashed their fifth album, "Mr. Simple". Yoon Jong Shin presented the boys with the song "Good Friends" for their new album, marking his second collaborative work with the idol group. He previously wrote "Disco Drive" for their second album. Despite the years between the two works, Super Junior remains the only idol group he has worked with thus far. On his Twitter, he wrote, "They've improved so much since four years ago; it was nice the entire time I was working with them. They're the only idol group I've ever given my songs to, so I feel that much more affectionate with them." The song is also meaningful in that the lyrics illustrate the years of friendship between the members themselves. A part of the lyrics state, "We were so young then, sometimes we'd put on a front. We'd get angry, our faces became red, at times we almost gave it all up. We never let go of each other's hands, though. I was so thankful then." Source + Photos: Joy News 24 via Naver
