When asked about his song topping music charts, the Super Junior member, "Who knew this would happen?...I think the fans and the fact that it's the fall season helped."

He also added, "It's an album that I've been preparing for a really long time, so I wasn't able to sleep last night. When I first saw the song climb to #3, tears started to come to my eyes without me realizing. I wondered if it was a dream... I had a lot of desire to sing. I hope that many people listen to 'At Gwanghwamun' and spend this lonely winter even lonelier (laughs)."

Kyuhyun also tweeted, "Thank you to everyone who came today!! My Ryeowook, Leeteuk, hyungs, my Changmin, and the pretty Lee Ji Ae announcer. And my ELF, thank you^^," along with the photos below.

As mentioned before, Kyuhyun topped all the major music charts' real-time ranking with his title track. Congrats on your solo debut, Kyuhyun!
