What's the story of the weather outside Elva Hsiao?

Outside the window of Elva Hsiao, the weather tells the complicated feelings of two people who were originally in love, but they have to forget, but they are reluctant to forget.

Complete lyrics of the original song:

It suddenly rained cats and dogs on the day you left.

The window I forgot to close is wet all over the floor.

It's cloudy and calm today.

I don't seem to remember that wet rainy season.

People always study hard.

Go to a good place

Don't always stay where you are.

I heard a friend talk about you.

During this time, your life has its highs and lows.

That's why you left me.

Has become your partner.

I'm just your past

Although I still miss you.

It sounds too emotional even for yourself.

Although I still love you.

It seems a little redundant.

It suddenly rained cats and dogs on the day you left.

The window I forgot to close is wet all over the floor.

Love! When you come with burning.

The lamp of pain in your hand

I can see your face and know that you are happy.

I heard a friend talk about you.

During this time, your life has its highs and lows.

That's why you left me.

Has become your partner.

I'm just a part of your past

Although I still miss you.

It sounds too emotional even for yourself.

Although I still love you.

It seems a little redundant.

It suddenly rained cats and dogs on the day you left.

The window I forgot to close is wet all over the floor.

Since then, I have made four Zhou Yangguang.

Whoa ~ whoa ~ whoa ~ whoa ~

This is just a window in my memory.

It hasn't cleared up yet

Although I still miss you.

It sounds too emotional even for yourself.

Although I still love you.

It seems a little redundant.

It suddenly rained cats and dogs on the day you left.

The window I forgot to close is wet all over the floor.
