^ There, there! Deep breaths!
I think SM did a really great job in promoting them (yes, the many teasers got a bit annoying after a while, but thanks to these 4382961 teasers

I now feel like EXO has been around for quite some time and I always have to remind myself that they're "only" a rookie-group!)
And I think it's totally fine to fangirl over EXO! They're a great group and each member is talented.

Like I said in another post, I think that their debut was the best since DBSK (and that was like eight years ago!).
