And so the girl began a mysterious, heart-pounding adventure, just for the summer... Redemption System 3310: Hey! Don't ignore me! Also, who is this elementary-school-boy-like rascal who runs off faster than anyone after pulling pranks every day, has negative emotional intelligence, and can't read the room at all?! Give it back its gentle, healing big sister! - First superpower: Seo is an orphaned girl with albinism. Her only asset is a rundown house where no one lives. By the roadside, she finds a little orange who has just come into being, with no memories and no idea what to make of the world. "It's okay. From today on, your name is Orangehead Number Two!" "Huh? Orangehead is bad enough, but why Number Two?!" "Because I kind of like the name. I want to save Number One for the dog I'll get someday."

Second superpower: Seo is a rich young lady from a privileged family. Her neighbors are the Tsushima family, who have a black-haired, doe-eyed little boy two years younger than her. At their first meeting, they can't stand each other. She covers the bandages the little boy treasures with adorable pig faces. The well-bred little boy puts on an obedient face and complains about her to his two guardians, earning her five extra lessons a week in the etiquette classes she hates most. But in the end, under the watery night sky, she runs away from home with him. The fireworks and clamor fall behind them. The little boy finally gets to wrap himself in the bandages he has longed for, and she can finally cut off her troublesome long hair. The pair bicker and banter as they make their way from summer into winter, feeling the wind of freedom on their faces. Bonus side story: Seo is the sole survivor of a serial killer's attack. Both her parents died in the cruel massacre. Full of righteous passion, she enters the police academy, determined to catch the killer and avenge her parents and all the innocent victims...
