I became my teacher's pet. Literally. Tonight too, I was given a choker to wear by my owner. Akane is deeply inspired by Todo, a fashion designer, and it so happens that she, his biggest fan, would work under him. Though Akane works for Todo, an aloof perfectionist, she's never had a conversation with him, let alone does he know she exists. Happy enough just to work near him, one day Akane happens upon a crying Todo on the roof of their company. What's more, Akane comes across a choker that was dropped and left behind on the roof where Todo was standing. After thinking it over to no end, Akane decides to return the choker, entering Todo's room to place it somewhere safely. Too late! "From today on, you'll be my pet", are the words Todo speaks over his new plaything as he points to a certain "area" of her body...
