Kostas never expected a wrong turn through Hogwarts to change his life. Hidden behind a forgotten corridor lies a room no one seems to know exists. Inside, mounted on the wall, is an old telephone that should have been dead decades ago. One night it rings. On the other end is Y/N. The catch? Y/N is living years in the future, while Kostas remains in the past. Bound by a phone that only they can use, the two build an impossible friendship in secret. What begins as cautious curiosity slowly becomes the one constant in both of their lives. Every late-night call chips away at Kostas’ carefully built walls, revealing someone far more complicated beneath the charm and cruelty. Neither of them knows why the phone exists, who created it, or how long the connection will last. They only know that every conversation risks changing the future—and every goodbye could be their last.
