K -pop Guys before debut

Note : I am not anti fans or something like that

These are photos : K-pop Guys before debut, NOT before surgery. 
Because I think there are some of them who had done surgery before debuts.
Some are born handsome,
And some are not very "handsome" just like what you see in the picture before their debut.
Well , there are a lot of changes,
but korean boys doesn't seems drastically change  if we compare them to korean girls .
