When I read Crisis I was all in a panic and wondering if he was under attack, in an accident, or something. I also pictured him using his City Hunter skills- hohoho.
But I'm glad he reacted calmly and in such a friendly manner. Although we can say, to not do so will not benefit his image, there are many times when you can be taken by surprise and have a different reaction altogether.
Look at Madonna when she received flowers from a girl at an event. She took them, then turned to her bodyguard/assistant and said, "I hate this type of flower."
Booooo. Madonna.
(I am kinda wishing I was the fan who got up on stage for Lee Min Ho!!!)
