In Order to Save People, I Jumped Repeatedly Between the Past and Reality

A person's life is always full of regrets, but they are often irreparable. Zhang Chengan, all his regrets in life were about her. After her boyfriend Jiang Yizhou died while rescuing someone, Yu Tong was reborn in the summer vacation after graduating from the college entrance examination. He also met his late friend Zhang Chengan. She believed that this might be an opportunity given by God, which not only allowed her to see the important people in her life again, but also gave her a chance to save them both. Later, as Yu Tong shuttled back and forth between reality and the past, his regrets were gradually made up for, and she got closer to the truth - he was the best Zhang Chengan. There was a knot buried in their hearts. He chose to be restrained and forbearing, while she chose to turn a blind eye, so they stayed away from each other after they met. Until Yu Tong returned to the past, the two lines began to get closer to each other again.
