[TOMT] [Song] Peaceful sounding song with lyrics such as "I will love you till the day I die"

I heard this song in a restaurant and tried SoundHound and a Google search of whatever lyrics I could pick up but I didn't get any results.

It was a peaceful nice morning song with lyrics including "I will love you till the day I die". The rest of the lyrics I'm not sure are correct but I'll add whatever phrases I think I picked up anyway:

"You could never understand..." "... Loving dreams" "I'm gone for 7 days..." "I don't know why.. I can't explain"

Please help me find it. I really liked the song. Thank you!

EDIT: Looks like this song will be harder to find than I imagined. I was in a Burger King and it turns out that they purchase licence-free music from a company called Freedom Music, who in turn gets their music from more obscure artists, making the song altogether really hard to find.

If anyone can actually find it though I'll be really grateful!
