I don't know why some of you are hating, disappointed or upset about D.O singing instead of Xiumin. I'm not saying this because he's my bias, I LOVE XIUMIN TOO! Like? Who wouldn't love him? But, what I'm saying is, can't we all just enjoy the music? I mean the three of them did a pretty good job, right? And you can't change that fact. So, what are you blabbering about?
