My latest craze! Kim Sung Soo! Can anyone tell me what show was it that he acted with Lee Donggun(picture below)? Please? PLEASE?

A basic picture of him in a western suit which is coincidentally what I like to see him in best! =))

Whee... I am so totally in love with that charming smile!

This is the show I want to know the name of. It looks very familiar... And yet so unfamiliar. Can anyone tell me the name? Please? I beg you!

Haha, his body isn't that fantastic but whatever! I still like him! =))

This is a dorky, cute and stupid picture of him in my opinion. I like! I shall post a picture I DON'T like of him later. 

Yeah yeah, he's so good looking like Matsuda, right? I don't care, your answer must be a yes! =PP
