歌名：How Long Will I Love You

歌手：Ellie Goulding

How long will I love you?

As long as stars are above you

And longer if I can

How long will I need you?

As long as the seasons need to

Follow their plan

How long will I be with you?

As long as the sea is bound to

Wash upon the sand

How long will I want you?

As long as you want me to

And longer by far

How long will I hold you?

As long as your father told you

As long as you can

How long will I give to you?

As long as I live through you

However long you say

How long will I love you?

How long will I love you?

As long as stars are above you

As long as stars are above you

And longer if I may
