 when i was 23  and you were 19
 we  first met on a cafe
 when i was 25 and you were 21
 we chose our own life
 it’s time to leave ..
 it’s time to leave each other..
 it’s time to leave..
 it’s time to leave each other..
 it’s time to wake up..
 i wanna fly back to that moment
 i wanna fly back to the cafe
 say hello ..say hello..say hello..say hello..
 say hello.. say hello..say hello  to you ..
 it’s time to leave ..
 it’s time to leave each other..
 it’s time to leave..
 it’s time to leave each other..
 it’s time to wake up..
 i wanna fly back to that moment
 i wanna fly back to the cafe
 say hello ..say hello..say hello..say hello..
 say hello.. say hello..say hello  to you ..
 when i was 29 and you were 25
 we both settled down and never met..
