Fun show. Five personalities as love interests. The outwardly hardened and strict teacher who's actually soft, innocent, and kind of helpless on the inside. The small punk girl who likes teasing boys and has a cutesy job where she acts completely different from her usual self in order to pay for her dreams to come to fruition. The slim, beautiful, and classy literary genius who suffers in other fields but wants to become an astrologist to be closer to her late mother. The short, busty, and short tempered mathematical genius who suffers in other fields as well, but has trouble reading people's emotions, so she wants to go into psychology. Last of all the hyper childhood friend who's an athletic genius, but requires proficiency in English for a recommendation to the university she wants to go with.

These are all kind of classic personality types, and of course they all have issues at home or in their past, but the kicker is its ending.
Harem shows often have a lot of trouble establishing a satisfying ending, with chosen formats for such endings often being complete ambiguity, or perhaps making it obvious who the protagonist will end up with in the end from the very beginning, like season 1 of Oreshura. An example of a well done ending to a harem-style show that leaves it without someone's favourite pick being left in the dust as the story author chose at random which of the girls the protagonist would end up with is the ending of season 1 of the Quintessential Quintuplets, where it works in complete ambiguity but still casts a short line in order to keep everyone satisfied.
The ending of this show gives a pretty affirmative answer as to who, in the far off future, the protagonist will probably end up with, and honestly they chose the best girl, don't get me wrong. However it also throws enough obstacles in the way of that answer for there to be hope for the other female protagonists. Where as the end of season one of Quintessential Quintuplets is good because it's a lot of ambiguity with a sliver of certainty, this show's ending is good because it's a lot of certainty with a sliver of ambiguity.

Last of all, near the end of the show there's actual character development for the male protagonist, which is very rare for harem shows, so that's always a huge plus.
