This anime has serious issues with tone. It takes a stock harem comedy and tries to make a more serious story in the last few episodes. Thus it deserves some points for originality (harem comedies don't usually try to explain *why* all these girls are attracted to the same guy). But because the actual storyline is so compacted into the last few episodes and is rather convoluted anyway, it can be seriously confusing. Watch it for the comedy, not the storyline.
