Did He Become a Movie Emperor After Leaving the Psychiatric Hospital?

As one of the patients in a psychiatric hospital, he got a System and became an award-winning actor (?) while wearing an utterly emotionless expression.

The System was clapping with joy, too (?)

Doctor: What are you doing? Please don't try to escape the hospital. This is simply a place where you can receive proper treatment for your condition.

The doctor pleaded with him earnestly.

But he had Cotard's syndrome.

And still,

he never understood what people were saying and continued doing whatever he wanted.

At first, the System inexplicably bound itself to him, and their "happy" journey began.

When he arrived in the Bungo Stray Dogs world, when he arrived in the Jujutsu Kaisen world, when he...

All the original characters were delighted. Confirmed, that's right, delighted. Don't doubt it; they were happy in exactly the way you think.

Green Tea. The black-haired boy said something horrifying without changing his expression.

"Wow. Big sis, you're so full of life."

A certain older sister: ??? Scared again.

Green Tea. The black-haired boy: "I'm honestly jealous that you're alive."

Dazai: ??? So you mean you're not happy to be alive in this world?

Lively. The black-haired boy greeted everyone in a lifeless voice. "Wow. I'm so happy to meet you all."

The Jujutsu Kaisen cast: You said that very nicely. Please don't say it again.

Theme: Everything can be happy and good, and that's all that matters~
