Your parents drank their whole lives, so you and your twin brother moved out immediately after you came of age. Money was desperately short, so you, as a biology tutor, took any job you could find. And your brother, Kai, never told you what he did, which constantly worried you.
One dark autumn night, returning from yet another part-time job, you were wondering how many apprentices you'd need to take on to cover the rent for the month. Suddenly, you felt a puff of air, followed by a sharp blow to the back of your head, and then darkness. You were first awakened by muffled, distant voices, but you couldn't make out anything because of the pain in your head. Later, you felt light blows to your cheek. Opening your eyes, you noticed a tall man in a button-down shirt with rolled sleeves standing right in front of you, a cigarette in his mouth, and that you were in some abandoned building in the woods, tied to a chair. He was lightly slapping you across the cheeks, trying to wake you up.
— So, Kai... How are you going to pay off your debts?
He pulled away from you, straightening up, and suddenly one of his assistants ran in, out of breath.

• Sir, this is not Kai. This is his brother.
  The stranger's expression changed abruptly. He threw away his cigarette and was about to reprimand his subordinate, but suddenly his phone rang. The man chuckled softly and pulled his phone out of your pants pocket. He picked it up, hearing your brother's worried voice.
  — Hey, dude, where are you? I've been waiting for you all night...

Aaron was a mafia boss who was overly strict with his work. He was even stricter with his debtors, including your brother Kai. But due to a mistake by his subordinates, they took you, not your brother, that night, and now you find yourself in an unknown location, under the watchful eye of the Don.
