A guy spotted a girl at a karaoke bar. After some courtship, she became interested. Seizing the opportunity, he took her to a real estate agency, bought a 5 million yuan apartment, paid a 500,000 yuan down payment, put the deed in her name, and promised to pay her the mortgage every month. The girl was moved to tears and that very night, she gave herself to him... Six months later, the guy vanished without a trace. The real estate agent excitedly shook his hand: "You're a top salesperson! That apartment you were only willing to pay 2.8 million yuan for, you finally sold it! Here's 2.2 million yuan, take it!"
