I wanted moar of Winter Garden. Starting as a cutesy shojo drama with a steady descent into madness. After a long string of misunderstandings and cameos of adult versions of all previous characters... girl gets boy, GOOD END.
I wanted Usada to be a ludicrously popular idolu. So popular she doesn't have friends, people only like her for the money or status she brings. Through an absurd course of events, she would befriend Puchiko (who had never heard of Usada before) and aid her in the quest for the guitar.
Puchiko would take all sorts of odd jobs to get money while refusing to accept any gifts from Usada. One job would of course be cosplaying as Mint Blanchmange for a kids' party.
After having their friendship questioned, Puchiko would ask Usada to step in as a support singer for the school musical performance in the grand finale.
