Wu Xinbei often wonders, if he used his bravery in the first 22 years less, then when he met Li Mu, he would not have so many regrets, and when he saw Tang Yi again, he would not have so much resentment. He hated Tang Yi, and even more, he hated himself...
Tang Yi often wonders, if he had not been so careless three years ago, if he had arrived at the airport earlier five years ago, or if he had not been so presumptuous and self-deceiving in the first 25 years, Wu Xinbei would have fallen asleep peacefully in his arms every day, with maybe one or two little ghosts next to him.
Unfortunately, there is never if in this world.
This is a story of chase and counter-chase, a story that tells everyone to be honest with themselves and cherish the people in front of them.
