Six Flying Dragons???

I search for the song in the last part of this video but I did not find what I need and i hope that i can find someone know it ^_^

I really loved the song and the collective singing ^_^

i wish you all a wonderful time (^_^)

Great! I really wanted the choir version! Thanks for sharing :D I already downloaded Byun Yo Han's version I really like it. I don't really like the rock version, somehow feels very out of place. Yoon Kyun Sang's version was a nice surprise ;) though he looked kinds uncomfortable there :P 

Does anyone have the song Byun Yo Han as Ddang Sae sings earlier in the drama? I have the version they show in the drama, but I want one without the characters talking in the middle.
