The Tutorial is Too Hard

A brief description of the manhwa The Tutorial is Too Hard:
It was just a boring day.

But suddenly a message appeared where I was invited to Tutorial – a new world.

I was also asked to choose a difficulty level from 3:
easy, normal and hellish.

Without hesitation, I chose the heaviest, hellish one.

And here I am in a new world, in vain I chose this level of difficulty.

I need to get out of this world…
