Once I finished the anime that left on a total cliffhanger (didn't even feel like an ending because it wasn't). I had to find out what happened, I was not disappointed in the least. It's cute, it's interesting, and it ends very very well on a very clever note. I had an ache in my heart when it was over.
*SPOILER ALERT*
I am so happy/relieved/refreshed to find a harem anime that ACTUALLY picked a girl and stuck with her. I have been watching/reading way too many romance "blue balls" anime/manga where they never commit to a couple.
