In a desolate world, they loved each other quietly. Amid the passing years, 27-year-old Li Yansen glanced back one day and suddenly saw the deep affection in Meng Xia's eyes as she watched him. He asked, "How long are you going to keep this up?" Meng Xia said, "Li Yansen, I can't walk away anymore. Only you can come and get me, and free me from the demons that have haunted me all my life. Aren't you coming?" Li Yansen watched the March breeze brush the loose strands of hair over her forehead across her face. Suddenly, he felt that without her, even the March breeze was bitterly cold. He suddenly wanted to go back and hold her. Their story begins here. It can return to the past, or reach into the future.
