If you expect to watch other than to see the daily behavior of these cute, innocent & beautiful girls. I suggest you forget your intention. I was surprised when I saw the score on MAL, because I think this anime is good enough for casual viewing while watching the cute behavior of innocent girls. But when I watched it again I just remembered about the side story in it. Because I was curious I tried to find out. It turns out that this anime was made to promote the game and in short the side story was just bait to get the audience interested. I suggestyou ignore the side story.

Although it is quite annoying because there is no certainty of the relationship between the side story and the main story, but I quite enjoyed this show. So if your expectations are not in accordance with paragraph 1. It's better to stop there.
