Does anyone notice how even before EXO debuted all the plans for them were already organized? I mean they must have recorded over 100 songs before debut they wouldn't have those teaser's before debut without recording the songs first. It's like SM somehow managed to construct the storh EXO will bring before they debut concepts like this dont come over night. Im truly amazed on how SM formulated everything for EXO tho 2 left us the story they put together long ago is still full proof.
