Windstruck

If you don't know the flick, this clip might looks pretty cheesy to you. BUT: If you have seen the movie, you will start to cry in about two seconds,- if you have a heart. Come on, show some feelings!
So please make sure that you have enough handkerchiefs.

I chose the "Knocking on Heaven's door" Orchestra version, 'cause it's a beautiful interpretation of that song,- and it reminds me on Ji-hyun standing at the roof of the skyscraper.

The second song is from MC Sniper - BK Love.

The last melody is called "Reunion Theme" by Kwak Yong Jin and is also available on the Windstruck OST.

I would say: Close your eyes and listen to the music, but then you would miss the video, so instead: Open your senses for a few minutes,... you won't regret it.
