Before he was a Riddle, he was Mattheo — the boy Y/n shared a cracked orphanage mattress with, the boy she promised she’d never leave. But she did. She got adopted; he didn’t. Years later, Hogwarts gets a new transfer student with a name she swears she’s never heard… until she looks into his eyes and recognises the only friend she ever truly had. He isn’t the boy she remembers. And she isn’t sure whether the version standing in front of her wants to forgive her… or haunt her.
