She didn't come to Hogwarts to fall in love. Especially not with him.. From the moment Seraphina Snape steps into the Great Hall, Mattheo Riddle is watching her.. dark eyes, unreadable smirk, and the kind of danger her father warned her about. Professor Snape watches her too, always close, always silent. No one knows why she's really here. But the Slytherin boys are curious. And curiosity in Slytherin is rarely harmless. She's a secret.. He's temptation. And the rules? They were never made for people like them..
