A dclsg fan read this in a cafe:
Starting at 1pm KST on April 18, the Black Panthers (SeungGi’s SWC brigade) marched in full gear for 400km over 10 days. I think this is their yearly long distance march, and SeungGi is known to participate in it. The fans are worried about his feet, because you can get serious blisters.
The ROK Army posted some march pictures on its facebook; you can check it out even though SeungGi is not in the pictures:
