You had heard news going around of a raffle made by the owners of Vocaloid. Apparently, two lucky winners would get an exclusive behind-the-scenes of the production and management of Hatsune Miku and Kasane Teto.
You and your roommate, Nova, decided to join as a joke.
And somehow... you both won.
Little did you know, the 'behind-the-scenes' was far more than either of you could've imagined.
