Harry Potter, an unpopular boy who lives in the storage room of his aunt and uncle, has many strange things about him.
Perhaps the most unusual thing among them is that he can talk to a non-existent boy, who calls himself Horry and temporarily lives in his lightning scar.
Horry seemed to be able to control Harry's body with his permission, but the two were very different in personality and appearance - one of Horry's eyes would turn red when he used magic - so at certain critical moments, Harry had no choice but to let Horry come out to the rescue and was seen by others, and rumors spread that the savior had a dual personality.
Even in the wizarding world, the existence of Horry seemed unbelievable. This was confirmed when Harry learned that he had a younger brother who died with his parents - Horry Potter.

As for why Horry's soul can escape into Harry's scar, I can't think of a good explanation. Let's just think it's a coincidence. Horry happened to be taken in when the fragments of Voldemort's soul splashed in.
It will fulfill some of the regrets of the original work. The cp is the two protagonists... Actually, I am not sure whether I will write about the emotional line, because I am really not good at writing about this aspect orz
Intention: to fill in regrets
