It is about a person, away from home, and went abroad to study, or to work... and they avoided their parents.. but found out that, they are struggling a little bit... and miss home, quite a lot, and regret a little bit... about their independent and rebellious ways. And is asking for "where are you now"... But the context is not said about actually.... just parent and child relationships. It could be extended to romantic relationships too. But in the video, it showed parents... only... It's quite romantic, if you understood it, it is the inability for the guy to express himself truthfully to his partner. But anyway, these kind of things, happen quite a lot.... wasting time... and not sure where the person which you fell in love with has gone to either.
Reminds me of a lot, when I used to call my mother from university... watching this back now, just bring tears to my eyes too. The struggle at universities, but letting your loved ones know that you are okay, and fine. So that they don't worry so. Sigh.... Even now, I struggle to say such words to my mother too.
