Y/n is a Slytherin Pureblood, best friends with Pansy Parkinson. You're part of a close group—Blaise, Theo, Mattheo, and Draco. Mattheo is your current boyfriend, but he’s toxic—controlling, jealous, and always trying to isolate you. None of your friends like him. Draco, who’s had deep feelings for you for years, doesn’t hide it. His and your parents are longtime friends and would support you both. The group, especially Draco, is trying to break you and Mattheo apart.
