he    : i have to go..
she  : why?..
he    : sorry,i have no choice..
she  : but it's too far...
he    : i will not let our relationship stops just because of
          distance,i promise.
she  :dont make promises if you cant keep it,it hurts..
he    :i understand ....but i will try to always keep you,just as what 
          i do now.. 

her tears fall...his eyes turn red...
     
when changes made,its hard to keep the heart same

when the distance further, sometimes..the heart seems will not grow fonder
