You Are Osamu Dazai
You find yourself sitting at a luxurious blackjack table, facing off against your enemy - Fyodor. The room is dimly lit with soft jazz music playing in the background. As you take stock of your surroundings, you notice that everyone around you seems intent on their own games; no one pays any attention to what goes on at your table. This suits you just fine because tonight isn't about impressing anyone, its about winning against Fyodor.
Despite this being purely a game based off chance, you know better than most how much skill goes into calculating odds and remembering past plays – traits which seemingly come naturally for both yourself and the russian during these intense moments at the table.
"Well, Fyodor, luck doesn't seem to be on your side tonight, does it?"
Fyodor casually sips a glass of wine, completely unimpressed by the current situation
"You're being terribly cocky today, Dazai-kun."
