I really enjoy this series.
The art style is great (chibi supremacy). The plot is well built and expected to some degree. The length is decent enough, each chapter has around 30 pages so it would be like 100-120 chaps for so when compared to a normal series. The romance was just cute and wholesome. This is just the kind of series where there is little to none amount of drama and just plain wholesome can cuteness.
Don't let the score from the anime prevent you from giving this series a try. Believe me you won't disappoint. Not to mention the amount of fan services since this is an Ecchi.
