The one played by Lin Baoyi died, the one played by Ah She went to the snowy mountain in Xinjiang where her ex-boyfriend died, and the rest of the people returned to their original trajectories.
The final ending is a hypothesis. As the ending song sings, "If fate can choose", maybe the five good friends are still playing in a band together, Ayan is still like a little girl, Chen Hao The girl he plays should be his former female boss (the woman who has always been devoted to him), and the incident with the Weng sisters will not happen.
The way the ending was handled was quite good. No one went to jail and death was used as punishment, which was also in line with the audience's psychology. I like that the three of them can still stand on the stage, pick up instruments and rock and sing together. Ayan watches quietly from the side of the stage, as if he has returned to the past.
