Mattheo Riddle and Y/N LeStrange have hated each other their entire life. Rivals at Hogwarts, enemies outside of it. But now, their parents have decided that they are to marry, and fake it properly. That means public fake-love, no cheating, and staying in the same room. Riddle is determined to avoid his new wife, and Y/N is doing her best to keep the secrets of her traumatic childhood as a LeStrange hidden. Unfortunately, tension and desire can’t be denied forever.
