Tears Are Falling

I just realized that I always been sad this past few months. I dunno what's wrong but I always feel that there's something/someone missing in my life and I really don't know what will make me happy. And this is my "emote" song. I listen to it when I'm sad. Almost every other day? almost everyday. Song from korean TV series "Pure Love aka 49 days" the only korean series that I have watched since I started working.
