Mattheo Riddle has always believed he can get anyone to like him. So when someone challenges him to make the one girl in Hogwarts who can’t stand him actually want to be around him, he accepts without hesitation. At first, it’s just a game. A way to prove he’s right. But somewhere between the arguments, late-night conversations, and moments neither of them expected, something changes. The girl who once hated him becomes the person he looks for in every room, and the challenge he started for fun becomes something far more dangerous. Because the only thing standing between them isn’t whether she’ll fall for him. It’s what happens when she finds out why he wanted her to in the first place.
