一又二分之一的夏天片尾曲(Let It Rain) - 尼坤
Let it rain
Let it rain
Oh I aint scared no more
Let it rain
Let it rain
I know I got you by my side
Like an angel
Like my mother
Like the bestest friend of mine
Like an angel
Like my mother
Like the bestest friend of mine
Like an angel
Like my mother
Like the bestest friend of mine
So I let it rain
