When Shen Guiyuan woke up, he found that he was trapped in his body.
Another is smiling with her face, speaking with her voice, and living with her name. That person has a system and a mission to get close to the current prince. After completing it, he can "go home".
Shen Guiyuan could not move, speak, or be seen. She only had darkness, and the faint voice in her heart in the darkness.
That person is not a bad person. She just wants to go back.
Shen Guiyuan is not a victim either. She's just waiting.
This is not a story about taking back your body.
This is a story about "two people who want to live".
Concept: No one is a bad person, but someone is deprived. Both want to live, and no one deserves to disappear more than the other.
