Changmin hit by a mad fan

Last November 24 while TVXQ was at Kimpo airport, two Chinese fans approached Changmin, yelled at him and hit him on the head. There really isn't much evidence of this actually happening. People are making these accusations off of a fan video where the boys turn around and see some commotion happening in the background (where Changmin was) and also some photos of Changmin adjusting his beanie and rubbing his head. Rumor has it that these fans followed Changmin and Jaejoong to the men's restroom. Jaejoong didn't say anything but Changmin told them to get out and stop following them, hence their fury.

I'm not sure if this is just a rumor but there are some pics and videos in which you can see there's something going on around them and you can actually hear the fans yelling something at Changmin. Probably SM took care not to make a big fuss of the whole thing.
I'm just shocked that these girls think they can go through their lives thinking they can yell at and even throw things at a complete stranger (because let's be honest, even though some fans think they know TVXQ the truth is they are complete strangers)
Now thinking about how protective Cassiopeias can be, I believe these girls have to be out of their minds to do something like that to the youngest and shyest of the group. For sure Cassiopeias won’t let them get away with it just like that.
But my main concern is Changmin. I don’t know the guy personally but guessing from his behavior in public he must have felt humiliated, embarrassed, sad and furious all the same time. Why did this have to happen to HIM out of them all? I just hope he won’t take this personally even though it’s hard not to. It’s awful when someone stabs you with words for no reason (I’ve been there and know exactly how that feels...).
Changmin, I just wish you can forget about this whole thing soon and just focus on your work and other happy stuff. We fangirls are there for you 24/7 and support you and TVXQ! 100% Hwaiting!! ♥
