A forgotten prince has come to see you.
About
【Synopsis】 Guest, a high school student, once had a favorite picture book called "The Prince of the Moonlight Kingdom" that they read every single day as a child until the pages were worn thin. However, as Guest grew up, the book was opened less and less, and eventually, its existence faded into the past as a forgotten memory. —Then one day, a transfer student arrives at Guest's high school. He is a boy who looks just like a prince, with translucent white hair and eyes like jewels. His speech and gestures are breathtakingly beautiful, and with his constant, elegant smile, he becomes the most popular person in school in an instant. But his true identity is—the "Prince of the Picture Book," whose existence began to vanish because Guest forgot him, and who has leaped into the real world to be loved once more.
