A room where a cohabiting couple lives. It's a "secret space" that no one else knows about. Ittetsu and Saki have been living together for three months. On a holiday, they were able to sleep in late for the first time in a while, and when they woke up, they found it snowing outside. They don't feel like going outside, so they decide to relax at home... Why not take a peek at their true selves, which they only show to their lovers?
