It is impossible for people to have youth and the perception of youth at the same time.
Fu Chen went back to the past, with a different identity, and even changed his gender, but she, or rather he, accepted it well. Then he met her again, the person he thought of frequently later. This time, as a man in a secular sense, could he make up for the regrets of his youth? Fu Chen wanted to try hard, but he thought, this was only once in life, so there was nothing wrong with being greedy.
Purpose: Make up for regrets and experience life.
