YD

Everyone thinks Cassian Rosier is the perfect boyfriend. For nearly two years, Y/N believed it too. Once, he was gentle. Attentive. The boy who made her feel beautiful and safe. But somewhere along the way, love became control, apologies became excuses, and the boy she fell for became someone who cheats, manipulates, humiliates, and hurts her behind closed doors—only to play the perfect boyfriend whenever anyone is watching. Y/N keeps making excuses for him. Until one night, Cassian goes too far. And suddenly, the Slytherins who thought they knew their friend are forced to see what he’s really like. Especially Theodore Nott. Because Theo has been watching Y/N disappear for months. And now that he knows the truth, he’s not going to let her disappear completely.
