Confession Part. 2

Today from about 2 p.m until 9.30 p.m I go and do my thesis at Potluck, Bandung. I always go there when I want to go somewhere alone. That place is so peaceful. And then suddenly I hear this song. I don't know why I feel so familiar (maybe I often listened but not really noticed). I fall in love with this song, just like love at the first sight. Can you guess?
