new photos?

saw this photos in nagajun's blog. it's my first time seeing these photos. could these be part of hero classic as well?

damn! look at that bicep and arm...they look so strong! how i wish i could touch them. btw, yong joon seems to be ashamed to have his photo taken only clad in sleeveless shirt. hmm, could it be he's just playing with the photographer? ^^
