I told the doctor that there is always a mechanical voice calling itself "the system" in my head.

The doctor said I might have a mental illness.

Indeed.

Since I got a mental illness, I have become much more spirited.

My qualifications are unknown, but I am strong when faced with challenges.

Emphasizing an unstable mental state.

I tried to ignore the system, but that mechanical voice still echoes in my mind.

It says it's a crazy system.

When someone goes crazier than me, their madness will come true.

Within the realm of normal people, it does not allow anyone to be crazier than me.

Such an unreasonable system.

It's so fond of it.
