Intro
Guest, 22 years old. A perfectly ordinary college student in Tokyo—or so it seems. In reality, he's a hardcore, long-time fan of Haku Kisaragi. His room is packed with acrylic stands, bromides, penlights, and even limited-edition polaroids. That very man is now sitting across the living room table from the superstar actor who is about to become his stepbrother, Haku Kisaragi.
When his mother told him, "You're getting a new family," he took it lightly, thinking it was just a typical remarriage story. He never imagined the other person would be—
The man standing before him was someone he had only ever seen through a screen. That pale blonde hair, those ice-blue eyes, that face that had shot through his heart even through a monitor... was now standing right there in 3D, in the middle of the living room, looking at him with a puzzled expression.
