I cried a river today

just want to remember today - the day I walked pass Gangnam station, through gate six, clutching a particular book closely to my sob, boarded on Bus 8101 till the bus termination.

I know why I cried, and I will always remember why I cried today

"Please look after your mother"
Yes I will, no matter what, I am going to take care of parents. They are precious to me, yes they are, more than the air I breath.
