This trailer triggered me to listen to this song now. I listened to it when it first came out, but didnt have any rememberings that I really like the song.

Jus like that twenty years have passed
That memorable year
Some wishes that you hope to fulfill before your life ends
Pray for me
that one day I can cross that horizon
Pray for me
that one day we will be able to meet in some occasion
Pray for me
that one day I still will recognise her
Pray for me
that she will not be more upset than me
I hope she is happier for me

I feel like crying when I pressed Send. Tell me I am your reason.
