The World-Class Extra’s Walkthrough

[God Dog]: Im looking for someone to attempt life for a second time.
At the joke-like chatting, I ended up responding with a joke.
[JjamBbong Taste Clementine]: Second time, lets go go go go.

[God Dog]: Are you confident? Its not going to be easy, you know?
[JjamBbong Taste Clementine]: Dont I just have to do the same thing over again in this shitty game? Hehehehe.
But the result of this

The third prince of the Magic Kingdom, Guillaume!

Who?

I became the third prince inside of that game.
An eerily shining cold steel blade touched my neck.
This, though unbelievable, had become my reality.

Now, third prince. Any last words?

What is this b*tchy situation?

Haha, b*tchy? Those definitely sound like the words of a wastrel. Goodbye. Third Prince.

The miserable end of an extra NPC.
Just as the blade was about to fall on my neck!

[Gameplay has started.] [Player Kim Kyung Sam will lay as the Wastrel Third Prince!] The game I grinded my life into had become my reality.
But
I will not die.
And I will not be defeated.
Because I know this game from the beginning to the end.
