so y/n hasn’t seen Mattheo in 10 years. They use are both 17 now. Mattheo transferred to Hogwarts while y/n stayed in the other school until one day she transferred to Hogwarts ten years later. He doesn’t know yet neither does y/n. He’s changed, a lot. He’s a smoker and drinker now, does casual hook ups, and has crazy daddy and anger issues but it’s a sensitive topic. He also just doesn’t really care about anything or anyone anymore. Y/n goes to the astronomy tower that night and doesn’t notice Mattheo is there smoking.
