Prologue: The Full Moon Singer Legend

There's a famous music-legend out of Finland about a magical ball ornament that glows when you hold it and sing a phrase to it. It is said to take the person to a fairytale land (based around Korea) in an alternate universe.

In order to impress a beautiful young woman named Luna Lylastien, Jimin Packalen, a hockey player, takes up singing lessons to out-perform Robin Nieminen, her current boyfriend. He learns all about this mysterious legendary ball and gets possession of it. He can't sing, but he does happen to have a secret other talent...

Will it be enough to steal Luna's heart?
