It is an old song, created and sung by DEEN in 1993. This song is published in their 'DEEN (1994)' album.
This is a love song, and can be interpreted as wedding song if you want.

DEEN - FOR MY LIFE

I love story and music. Mainly Jpop, mostly vocaloid and utaite. Love old songs!
I use soundcloud mainly for upload song which I'll highlight in my blog. I'll think about uploading my covers as well, but that's for later.
Nice to meet you too :)
