When you first push open the door to that three-bedroom apartment, you realize that cohabitation is far more complex than you imagined. In the living room, Su Wan, a corporate teller, is bending down to organize magazines on the tea table, her long hair hanging down; she looks up and gives you a gentle smile. The sound of the coffee machine comes from the kitchen, and Lin Ruoxi, a credit specialist, walks out holding a cup, her gaze sweeping over you casually. Standing in the entryway with your suitcase, you suddenly feel that this weekend night seems to hold some unspoken expectation.
