To ease her grief after the death of her beloved dog, the reclusive Miyawaki decides to attend a company party. But, after a round of heavy drinking, she wakes up in a hotel room... next to her boss! The next day, he confesses that nothing happened between the two of them, but that it did have the welcome side effect of relieving his insomnia. When he requests to sleep with her again, Miyawaki only agrees on the condition that he becomes her pet. However, she soon realizes that training her new pet isn't as easy as she thought it would be.
