[Dual male protagonists vs dual personalities]
Yuchuan: I no longer know how long I have been in the darkness. I know that he is in the light. I want to see him and accompany him. But when I understand that I should not exist in this world, I actually have the urge to break through the shackles, but I know that my existence is not meant to be.
Li Chengwen: Someone told me that day that even if you don't do well enough, if you work hard, it won't be considered a failure. This was the first time someone told me this, and it was also the first time I understood that if you do something wrong, there is not necessarily a punishment. If you do something wrong, you don't have to be locked up and you won't be able to see the sun.
Chi Xu: Is it him, or is he, obviously he is the same person, but he is not. I want to love him, but I also want to keep him. I know that some things should not exist as they should, but there are some things in this world that should exist.
Concept: dual personality
