The tune sounds like a pop song from very recent years, which was sung by a female singer.
It's on the tip of my tongue but I can't quite pin it down.   I can just about hear and picture the young woman singing it on TV.

Oh! I know what it sounds like!   The instrumentation makes it sound very different but it reminds me of ">Suzanne Vega's "Tom's Diner"/
At least the beginning of your video sound like that tune.
