I don't know when I appeared, nor who I am. I only know that I share the same body with Voldemort, but he doesn't know my existence. . . . I thought I would continue like this, hiding deep in the consciousness of a demon king, until I died. An unexpected action caused the Dark Lord to disappear, and I became a man named Bean. Riddle's waif. I am walking in this bright world that I have never touched before, and I just want to know what is my desire?
In short, it is a process of unconscious personality searching for self and true love.
The souls who grew up in Voldemort's dark world and Snape saved each other
The ending is definitely HE. The author is absolutely my own mother.
