I really really like this song. I really like EXO their one of my favourite groups. I wasn't a very big fan of their latest comeback, it took some time for Monster to grow on me but now I see how good it is. Anyway I woke up this morning to see my notifications blow up with EXO, let me just say that I was very surprised because I didn't watch any teasers, so what I saw was really surprising but also kinda amazing. WELL DONE EXO WELL DONE.
