I will say I quite enjoy it. Especially the pretty carefree second season. It's very cute.
But, no. I can say it doesn't seem like you would like it. Apart from the first couple episodes of season three, and maybe around the end of season 1, (but I can't quite remember, since I watched it before the second season came out.), it generally has a lot of fan service. By technicality it's not really a harem, but there are elements of one still, there are a lot of male characters. None of them are plot important apart from the protag, though. Besides maybe that demon guy that is introduced in season 2, but not that much. So yeah, giving my input here.
