Short Summary During the Second Wizarding War, Y/N and Mattheo Riddle—the son of Lord Voldemort—find themselves fighting on opposite sides. Though Mattheo has loved her for years, he remains loyal to his father and the Dark side until he witnesses Voldemort cast a Killing Curse at Y/N on the battlefield. Believing her dead, Mattheo abandons everything he has ever known and joins the fight against his father, helping the Light side win the war. After the battle, he discovers that Y/N survived the curse and refuses to leave her side, waiting desperately for her to wake up. When she finally opens her eyes, Mattheo realizes that choosing her was the easiest—and best—decision he ever made.
