Key to my heart

I'll give you the key,
the key to my heart.
I'm trusting you with it,
because i love you long time.

This key opens everything,
so you better be ready.
I've got sadness as well,
but its hidden from sight.

This key shows you just,
how much you mean to me.
So I'm trusting you with my heart,
hoping you'll look after it.

So this is the end,
i hand you the key.
Now just promise,
that you love me.
