I said no songs but that doesn't mean no videos~ Ahahaa~
Okay, this one. Well, no one does a video as carelessly as them.
Or perhaps they planned it this well since it's cut and edited. Idk~
But enjoy. 
Happy white day! 
I'll wait for Black Day and eat Jajjangmyun and mope.
JYJ- So childish in their late twenties. What's wrong with Junsu?
