Min Do-Hyeon (Acted by Lee, Ji-Hoon)
He's such a gentleman with good manners. He always seems neat and refined. He doesn't talk much. But he knows how to be terse and quick to the point. He's been successful throughout his life, but he's not interested in competing with others. He's very cynical; nothing really matters to him. He detests people who are obsessed with success and struggle to win. Nevertheless, he always wins and gets what he wants. He's the type of person that average people love to hate (top pic).

Han Seung-Wan (Acted by Kim, Jae-Won)
He's young and immature. He's a party animal. He's a very moody person. He's a frequent patron of the dance clubs around town. He's always welcome because he knows how to have fun. His father owns a mineral water company. He's handsome and cool, so he's popular everywhere he goes. And he secretly enjoys the fact that he's popular. He believes that women can't help but loving him. He has the characteristics of Don Quixote and Peter Pan at the same time. He majors in aeronautics. After graduation, he becomes a co-pilot for Sky Castle Airlines.

If you all have the money to spare can consider this show. Some of the scenes are shot in Singapore...overall quite touching. I like the part where Kim Jae Won fly the plane...coOL;)
