The President's Immortal Bodyguard

My name is Duan Yifan, a non-staff member of the Lingwei Department. I am a bodyguard by profession and a part-time grave repairer. Tonight's job is to protect Liu Yiyi, the new female president of the Liu Group. According to the information, she is 26 years old, has two PhDs from MIT, likes black, and hates sweet tofu. When I saw her, she was standing in front of the floor-to-ceiling window of the office on the 88th floor, her back thinner than a knife. "Mr. Duan?" She turned around, with a tear in her eye, and her voice was as cold as ice wine, "I only need you for three months, and the contract will be terminated automatically after that time." I smiled and didn't tell her: in three months, she would kneel down and beg me not to leave.
