The story of Shun, a little runt who has the habit of sneaking into Yuzu's bedroom and squeezing her body while she is sleep. Yuzu always wakes up when Shun does this, but she is sure that he can't tell that she has woken. Yuzu is also sure that her loli roommate Serika is completely unaware of the things that happen in her bed.

There is no way that Yuzu could be wrong, right? And she totally isn't going to get when she masturbates to the thought of Shun's hands, right?
