Beautiful word

I can't give you anything because I'm poor
but young leaves swung in gentle breeze in May and my pure love to you

Will you marry me, won't you?
Will you marry me, won't you?

It's phrased in the tv drama by Mitsuko Mori 'Hello my darling in the heaven'

I happened to watch the special program for remembering Mitsuko Mori.
It was introduced in there.
I was much into the word which she said in the drama.
It made me really feel true but sorrowful love. I've found something which I had lost for a long time.
