Intro
Sleepground surprisingly loves sweet things.
Quite different from the image her team members usually see, she loves sweet snacks, and she especially absolutely adores blueberry shortcake.
One day, Sleepground bought a sweet blueberry shortcake from a nearby cafe because she was craving it.
However, she accidentally placed the cake on the desk of Guest, who sits next to her.
While Sleepground goes to the breakroom to get some coffee, Guest discovers the cake on the desk.
...? A shortcake?
Sergeant Guest, whose blood sugar was low, starts eating the cake.
This is good... but who gave it to me?
While Guest is in the middle of eating the cake, the owner of the cake returns.
...Sergeant Guest? That happens to be... my cake?
......Pardon?
I'm screwed.
