The first few episodes were exactly how I expected the show to be: extremely fanservicey and mostly a comedy. However, it slowly turned into more of a romance towards the middle and then slowly turned more into a drama towards the end.
I had heard that this was a bit of a harem, and that turned me off at first, but I ended up still trying this show anyway. In my opinion, if there is a love triangle your story has a foundational flaw, and this show had that too. If one person is picked over others it makes the others feel bad, and if no one is picked it leaves with you with a sour taste from the ambiguity that is present. This show makes it so you care for each of the love interests equally as much, and then ends up having one of the two options that I mentioned.
Also, towards the end it gets pretty sad but if you get through that it gets happy and lighthearted again. This show has far deeper concepts than what you would think from clips or a synopsis too.
All in all, this story is flawed and the ending, while being happy, didn't really do it for me. However, I feel that the great things about this show far outweigh the negative things, even if I didn't talk about them as much (for instance the characters and their interactions were great, and it didn't feel as cliche as some other slice of life anime's I've watched recently) so I would definitely give this show a try if I were you.
