Music that gives chase

This piece of orchestral music comes from a Korean drama. I like to listen to it because it’s a sweet melody but with a racing tempo, that’s not unduly loud.

It opens unsuspectedly as a sentimental adagio, gradually picks up speed, hastens you on, cools off at an appointed time, then gives chase again! And with the sound of slamming cymbals, it calms down to end. So this is exactly the kind of rendition that makes me pump up the volume!
