Regulus’ first crush was Newt Scamander. He would always reread fantastic beasts just so he could get to the picture of him at the end. He didn’t really understand why he would start to blush if he looked too long. His dreams were filled with curly golden hair, high cheek bones, and a tiny smile that he wouldn’t mind kissing.
His passion for magical creatures would bleed into his fascination for this man and vice versa. This was why he loved them so much.
This was also why, a few months after first getting the book and sitting with his brother on the train ride to Hogwarts, he could barely look Remus Lupin in the eye without his whole face going red.
