Is no doubt 2PM.

They aren't pretty boys (like most kpop groups, and i have NO problem with that) but they are Y MEN.

I'm sorry.

If you think it's someone else, fine, but allow me to persuade you.

Just go watch A.D.T.O.Y, My Color, Hands Up, Without U and Comeback When You Hear This Song.

Then come back and tell me you agree.

BYE.
