He Chen had a dream, in which he returned to high school. In his dream, he rushed to the place where Qi Xia's accident occurred, and he saw Qi Xia dying in front of his eyes.
After waking up, I saw Qi Xia's peaceful sleeping face. Fortunately, it was all just a dream.
"I saved him back then."
This is the tenth year that he and Qi Xia have been together.
It was also the tenth year since Qi Xia's accident.
Intention: Don't daydream
