You and Mattheo Riddle have hated each other for as long as anyone can remember. He always has something to say — a cruel little remark when you walk into class, a smug comment when you answer a question correctly, a deliberately irritating nickname he knows gets under your skin. You give as good as you get, and neither of you would ever admit how much attention you pay to the other. Then summer happens. You return to Hogwarts looking completely different. Confident. Fitter. More self-assured than ever. Suddenly, everyone seems to notice you. Boys who never looked twice are finding excuses to talk to you. You have people asking you to Hogsmeade, leaving notes, flirting with you between classes. Everyone notices. Including Mattheo. And somehow, that only makes him more unbearable. He insists he couldn’t care less who wants you. If anything, he seems determined to remind you that he’s still your biggest hater. One night, big regrets.
