Making the world right is never easy. I work as a moneylender, a business with a bad reputation, but I still wanted to believe in people. My junior K was hardworking and patient, yet hopeless with money. When we met again after several years, he kept delaying repayment while sinking deeper into debt. Desperate to make him change, I offered to postpone the interest if he filmed himself having sex with his wife—a wager I was certain he would never accept.
