What is the square dance song with the lyrics "I wish to turn into spring rain to protect the flowers"?

Angel's Wings

Seo Yuteng

Fallen leaves with the wind, where will they go

Leaving the sky a beautiful scene

The sound of the once fluttering

Like Angel's Wings

Scratched through my happy past

Love has come to the place

With yesterday's fragrance still in it

The familiar warmth of the past

This is the first time I've been to a place like this, but I don't know if I'm going to be able to find it. The familiar warmth

Like an angel's wings

Crosses my boundless heart

Believing that you're still here

Never gone

My love is like an angel's guardian

If life goes on until here

There's no me from now on

I'll find an angel to love you in my place

Love has come before I've been here before

It still smells like yesterday

The familiar warmth

Like an angel's wings

Crosses my boundless heart

I believe you're still here

Never gone

My love is like an angel's guardian

If my life goes on till here

There's no me anymore I

I'll find an angel to love you for me

Believe that you're still here

Never gone

My love is like an angel watching over you

If life goes on till here

There's no me from now on

I'll find an angel to love you for me

I'll find an angel to love you for me
