Xiang Yu was thinking about Song Huaishi until he died, wondering if he could set off another fireworks for her. But Song Huaishi knew that Xiang Yu's death had been heard from others. Xiang Yu died of illness forever, and in Xiang Yu's memory was the 17-year-old Song Huaishi. But Song Huaishi was no longer 17, only Song Huaishi moved forward. Song Huaishi let go of his eight-year love for Xiang Yu, and he fell in love with Wen Wan, who had been chasing behind him. Perhaps Song Huaishi would never know how much Xiang Yu loved him. I still can't let go. Both of them broke their promises. One died at a prime age for the health of the people of the motherland, and the other bid farewell to the past to find the true love of his own. Xiang Yu has not let go, and in her memory there will always be only 17-year-old Song Huaishi.
