The Supreme Wand of Hogwarts

[GGAD, soul penetration, the protagonist has no cp] Robert knew from the moment he woke up that he had traveled to the world of "Harry Potter". She became an artificial male Veela, with an identity that was difficult to understand on either the magic or scientific side, and lived in the castle as Gellert's granddaughter. In this way, Robert, who had the memory of the original work, reached the age of 11 under the guidance of Gellert. However, Gellert, who had watched the entire set of "Harry Potter" through Legilimency, looked at the owl flying in the wind with worry. This is the first letter Albus has ever sent to himself, and perhaps, like the so-called original, it is also the only letter he will send in the next six years. "Then I will help grandpa chase him back."
