A train departs Beijing, China, bound for Moscow, Russia, passing through Ulaanbaatar and crossing three countries and all four seasons. The journey takes 127 hours and 50 minutes. They make the trip to find each other, and to forget each other. Clever and kind, decisive and resilient Su Nanxing and sly, handsome, sunny, self-obsessed He Anhao had nothing in common. A journey brought them closer. A chance encounter on the eve of college, followed by ten years of tangled ties: their presence in each other's lives became both the greatest gift and the greatest revenge. One stubbornly held on while the other fled in a panic, and so they remained entangled for ten years.
