By mistake, Xu Zhijian met him who had disappeared for a long time. They held a grand wedding and lived happily together. Contrary to expectations, he became critically ill.
When Xu Zhiyi woke up again, he saw the snow-white sheets and realized that he had been in a car accident and became a vegetative state, and that he came from Xu Zhiyi's dream.
He died that winter three years ago.
Purpose: Love time travel
