EXO is what thousands have waited for. Their debut was flawless, as perfect as 12 boys could have pulled it off. But behind all these success, what was behind the scenes?             Clarifications: Yes indeed it will be a story of Exo-M (but mainly LuHan!)   It will (hopefully) be not too dark—it’ll probably get better in the middle   It's my first EXO fic :) so be merciful thanks.
