風的季節 [The season of the wind] - Paula Tsui 徐小鳳, Anita Mui 梅艷芳 {Cantonese}

This song was used in the first episode of The Unholy Alliance - 同盟

I wasn't aware the summer has already past until I feel the wind blowing.
It passed away just like time.

I think about the good time that I had and felt sad.
I just want the wind to blow I tears and sadness away just like how it blow away summer.
