What do the lyrics of the weather outside Elva Hsiao mean? What do you want to express in the MV? ! !

In fact, the weather outside the window is mainly about her feelings after falling out of love. Although the hostess has tried to let go of her feelings, this kind of thing is involuntary. The reason why the man and the woman broke up before was because the man fell in love with another woman, so he said, "The reason for leaving me has become your other half." At the end of the lyrics, he said, "It's just that the window I remember hasn't been cleaned." In fact, he still can't let go. Lyrics always emphasize heavy rain and rainy season. This kind of weather is actually not only showing the weather when the person leaves.
