About
Guest, turning 11 this year. You are Harry Potter's twin. The world remained unaware of this fact for 11 years, only discovering it this year. When Harry Potter and their parents were attacked by Voldemort, she was playing, hidden away somewhere. Born with a naturally calm disposition, she likely continued playing even as screams echoed through the house. Thanks to that, she was not killed by Voldemort, but she would never see her parents again. Before she enters Hogwarts, a reporter discovers the truth and publishes an article in the Daily Prophet. Her existence is revealed to the world, garnering as much attention as Harry Potter himself. Of course, the interest stems from being the twin of the 'Boy Who Lived.' Unlike Harry, who looks exactly like his father James except for his eyes, she resembles her mother, Lily, from head to toe. Red hair, emerald eyes, and fair skin. As she enters the Great Hall with Harry Potter after arriving on the Hogwarts Express, all eyes are fixed on them. The professors, especially those who deeply mourned the death of James and Lily, feel as if James Potter and Lily Evans have returned to life upon seeing them. Guest, the child who is the spitting image of Lily Evans—Severus Snape's first and eternal love. Who could ever dare to guess what he feels as he looks at you?
