HP: First Experience in the Magical World

Accidentally traveled through time and started in an orphanage. Unexpectedly, he learned that he had arrived in a magical world and became a wizard. Shock! Muggles become wizards! What? Going to Hogwarts? OK OK! Thinking that he was not in the same class as the main character group, he thought that school life would be calmer, but he ended up being targeted by Snape. Original heroine Viola Brand x Severus Snape. Hope to save all the troubles. New author, please understand~
