tl;dr: A light manga about a girl so happy that she can make the reader feel happy, but that is incredibly repetitive with no plot. 

This is an episodic manga about a girl who has fun on her own and is perfectly happy doing so. The way each episode is told is from the perspective of someone watching her, often her butler, but others as well, as she completely defies their expectations and manages to have fun by herself. This is from where most of the humor arises. Plus, the art is pretty solid in that it’s cute and makes her look really happy, which is nice and actually pretty heartwarming considering the context and feels like a pretty strong inspiration to loners. The thing though, is that there’s no story beyond that at all with the characters all being pretty flat and simply to hold up the humor. Hence, this structure while enjoyable enough on its own, quickly gets repetitive, as it’s that exact structure for every chapter.
