Lee Min Ho's fans notice everything and devour every detail about him. When he showed up looking exceptionally handsome in a bluish-grey jacket with shearling collar, eagle-eyed fans caught a quick moment of Lee Min Ho's hand touching another person's hand, and fans' lenses zoomed in on the action. Take a look at it yourself, and tell me what you think. Was it a secret handshake, or something else?

But first, let's enjoy looking at beautiful Lee Min Ho in his beautiful jacket. He was at the Incheon airport flying out to Nanjing, China for a Semir event.

Here's the view from the back. It is a very nice-looking jacket, isn't? I simply love the striping along the full length of his arms.

Of course we need to see his handsome profile from the side too.

See Song Ha Yoon and Teen Top’s Changjo in the lighthearted fantasy comedy Sweden Laundry:

So here's the mysterious hand-touching moment. It could be interpreted in quite a few different ways. Is this guy giving support to Lee Min Ho? Is this a greeting between pals? Is it a secret handshake?

Zoom in for a closer look:

Would you like to see the YouTube video accompanied by music? It's even in slow motion.

(Despite the video showing 2014.09.06, this scene took place on December 6, 2014 at the Incheon airport.)

I'm thinking that the other guy passed a little slip of a paper or something to Lee Min Ho, who then put it away into his pocket. Do you see what I see?

Fans also noticed that he got a new haircut. Did you notice that too?

I'm in awe whenever I look at the handsome Lee Min Ho, face and all. At the same time, I can't imagine how he must feel living under such scrutiny from his fans, but our perfect man has always maintained a calm composure with a smile as he waves to his adoring fans.

So, what you think the hand-touching moment was about? Post your comment below.
