The story takes place in arc 2 from the perspective of Beatrice as she notices some changes in interactions around the mansion. One of them, being that the inhabitants are treating her much more casually than before, utilizing her door-crossing ability for their daily needs much to her annoyance, Ram asking for help in creating a shortcut for the outside to hang clothes, Rem asking for a quick way to the kitchen and more. The final straw is reached once Subaru enters the library with only his underwear on while completely soaked due to puck overusing water magic on him, begging to be taken to his room before anyone else sees him, she complies but scolds him harshly for entering a library like that. To avoid this situation, she attempts to stay outside the library for a day, only to see Subaru and Puck having a serious conversation in the hallway, she quickly hides into a room not wanting to be bothered and is surprised when Puck enters it to train poses. Beatrice later thanks Subaru, since she guessed it was Subaru's doing that made Puck do these poses, much to his confusion as he thinks she is mentioning the time he flashed her. This story has ties to The Great Spirit Puck's Nyan Nyan Sunny Day and The Great Spirit Puck's Nyan Nyan Nyan Sunny Day.
