One of the lyrics of the duet between men and women is "What's the name of the next life?

Lyrics:

A beautiful postcard appeared in the mailbox.

In the hut at the foot of Castle Peak, smoke from kitchen chimneys curled up.

But what surprised me was the back.

Your familiar handwriting is separated by years.

That remark was a joke when you left.

Dust accumulated in my heart into a tower.

You just brushed it off.

I'm still a puppet in front of the mailbox.

The thread is waiting for you to pull.

You said that if I remember you in my next life,

Even if we die, we will be together.

It's like a hypnotic instruction.

I'm in a coma again

Well, in the next life, if I remember you in the next life.

Don't forget your vows.

This is just a postcard.

I followed it into the next cycle.

That remark was a joke when you left.

Dust accumulated in my heart into a tower.

You just brushed it off.

I'm still the puppet in front of that mailbox.

The thread is waiting for you to pull.

You said that if I remember you in my next life,

Even if we die, we will be together.

Like a hypnotic instruction.

I'm in a coma.

Well, in the next life, if I remember you in the next life.

Don't forget your vows.

This is just a postcard.

I followed it into the next cycle.

Lost in my fuzzy air

I look for opportunities between your lines.

You said that if I remember you in my next life,

Even if we die, we will be together.

It's like a hypnotic instruction.

I'm in a coma.

Well, in the next life, if I remember you in the next life.

Don't forget your vows.

This is just a postcard.

I followed it into the next cycle.
