I used to be so happy

But without you  here I feel so low

I watched you as you left but I can never seem to let you go

'Cause once upon a time you were my everything

It's clear to see that time hasn't changed a thing

It's very deep inside me but I feel there's something you should know

I'll never forget you

You'll always be by my side

From the day that I met you

I knew that I would love you till the day I die

And I will never want much more

And in my heart I will always be sure

I will never forget you

And you'll always be by my side till the day I die

~ Never Forget You, by Alex Schulz

This song is just beautiful, and it also has a remix or a sort of cover by Zara Larsson, so check that out too.
