{wizard x muggle} Nobody in apartment 4A knows how to act normal. Theo Nott, Mattheo Riddle, and Enzo Berkshire are loud, chaotic, emotionally avoidant, and somehow always one bad decision away from setting something on fire. Then Y/N and their best friend Scar move into apartment 4B directly across the hall. What starts as shared walls, stolen food, late-night conversations, and constant apartment chaos slowly turns into something much more dangerous for Theo Nott — because the more time he spends around Y/N, the harder it becomes to ignore the fact that he’s getting attached. Which would already be a problem. If Theo wasn’t also hiding an entire magical world right across the hallway.
