There is a sentence in the lyrics of the square dance that the sun went yesterday. What song is it?

Lyrics: Yesterday's sun went away.

I feel tired after being cheated.

And today's mood is a dream.

You are a world that I can't understand in my dream.

My sadness

I was alone in the cold darkness.

Miss you with yesterday's memories.

What is the difference between yesterday and today?

I'm lost.

I'm lost.

I wander in the dark.

The sun left yesterday.

You are a world that I can't understand in my dream.

My sadness

The sun left yesterday.

I feel tired after being cheated.

And today's mood is a dream.

You are a world that I can't understand in my dream.

My sadness

I was alone in the cold darkness.

Miss you with yesterday's memories.

What is the difference between yesterday and today?

I'm lost.

I'm lost.

I wander in the dark.

The sun left yesterday.

I feel tired after being cheated.

My sadness
