I rated this story OOC. Have you read Harry Potter and the Half-Blood Prince? Snape's father was a Muggle. He had wizard blood only on his mother's side. Also, Snape was a classmate of James Potter. Lucius Malfoy is several years older.
Thank you for your review! I'd just like to point out that, as specified in the story summary and in the warning, this story is an Alternate Universe.
