A dclsg fan found this somewhere:
I went to a Dream Concert in 2006 or 2007, and Lee Seung Gi was an MC there. I sat in the section in front of the MC seats. Then my asthma flared up, and I couldn’t even breathe. But if I were to walk out, I would have to ask people sitting next to me to excuse me, and I didn’t even have the strength to do that. While I was gasping for air, Lee Seung Gi saw me from his MC seat, and he called a security guard who got an ambulance for me to leave. I was already grateful, but that wasn’t all. He asked me if I was ok, even got water for me, and he seemed really concerned. I was so touched that day. My mom and I then became his fans.
