I travel back again and again just to meet you again. No matter how difficult it is, I still want to see you. Lin Qingying, I miss you so much.
Before the first repatriation, Bai Yihan had been in the dark abyss, like a walking zombie every day. Finally, for 12 years, he fulfilled Lin Qingying's long-cherished wish. He shot and killed himself, but he did not expect that he would return again. He would see the person he had missed for a long time, and he would often relapse after that.
