December 30th 2006 KBS Gayo Big Festival
+ More images of him with the mask ;) The above was shared in the previous picspam, just so everyone is sure =)
I think his hair looks so adorable here XD
+ You can download a short video of the opening here, which is uploaded by kaldereta, here. If anyone has more or better quality images, please share? Hahaha I've been searching for related images for so long.
Edit:
+ And yes, a zipped file for the previous picspam has been uploaded here. Sorry I didn't think of zipping it earlier, because after all it's a spam and you will most likely have the photos already. Images in this post are included =)
