Whose song is the rain cloud in the wind? Help the gods.

Mai's lyrics "Clouds made of rain in the wind": Clouds made of rain in the wind are full of rain in their hearts. These are all clouds formed by the rain in your wind. A cloud made of rain is broken in the wind, I don't know where it will blow, and I can't find a trace of pity floating everywhere. I'm waiting for you to come back thousands of miles. Whenever the sky rains again, there is a cloud made of rain in the wind, and I think of you again in my heart.
