Waiting in the security line can be dead boring. Apink's Eun Ji, who is known for having fun with her fans and reporters, was enjoying some fun banter with those who were wishing her goodbye.  A friendly stranger in line behind her also waved to reporters as the pictures were being taken.  Eun Ji quickly joked that he was her boyfriend.  Our handsome stranger was quick to deny it, but laughed at the joke, since his real girlfriend was behind him. Good thing his girlfriend was also a good sport about it. 

Here's the video that has been going viral over the last few days.

How funny was this?  How would you react if your boyfriend suddenly found himself in this situation?  All I can say is what a fun airport memory.
