Knock! Knock! Knock!
Who is this ?
I’m your childish, let me in.
No! No! No!
You can’t come.
I’m mature now, let me be calm.

Knock! Knock! Knock!
Who is this ?
I’m your happiness, let me in.
Wait! Wait! Wait!
I’m too busy.
I have to earn lots of money.

Knock! Knock! Knock!
Who is this ?
I’m your enjoyment, let me in.
Stop! Stop! Stop!
Don’t you come.
I have a lot to done.

Knock! Knock! Knock!
Who is this ?
I’m your death, coming in.
Please! Please! Please!
Not now please.
I’m succeed but haven’t experienced the taste of life yet.

Knock! Knock! Knock!
Who is this ?
It’s you, yes you.
Let you in.
Don’t say no, it won’t harm.
You can earn whatever you want holding its hand.
Don’t repent or regret later.
