Puppy-like middle schooler's father remarries and he gets a cute cinnamon roll-like older stepsister who just wants to cuddle him like a puppy. And, that's pretty much all the plot one can comfortably fit into 3 minutes per episode. Animation is attractive, with a short plot and cute character interactions. I wasn't as impacted by the ending song as I typically prefer after a show. It felt more like just a complimentary afterthought. Still, it is rather pleasant to enjoy a change of pace like this once every so often. Enjoyment gets 10 out of 10 from me. Short, sweet series gets a short, sweet review.
