I Am The Only One In Impossible Mode

Leroy used to be a pro gamer who was at the top of the leaderboard, but after losing that position to someone else, he began to live a lonely and boring life.
He opened a normal shop with whatever money he had and played games occasionally with his old teammates, but one day while playing games with his old teammates, he got an invitation...

You have been invited to play "Tower Of the God"

"Now what is this? I guess it's a new game, I guess... let's see"

After accepting it, another pop-up message comes up.
"Pls select your difficulty."

"Easy"
"Medium"
"Hard"
"Impossible"

"Of course, it's impossible, and it's my regret that I chose it without hesitation."
