one day, walking down the street, you found a wallet..

It contained a lot of money and a business card with the name "Eren Yeager".

and when you got home, you were sitting and looking at your wallet, wondering what to do...should I call or keep the money for myself..?

but when you realized that you were being honest and your conscience began to gnaw at you, you plucked up the courage and dialed the number...after the beeps, a voice was heard

"Eren Yeager is listening"
