This is perhaps the most competent I've ever seen a harem-ecchi rom-com manga written. For the most part, it accomplishes in a chapter what its contemporaries would do in an entire arc (which shows how drawn out these kinds of stories typically are). The characters, though not original, are handled well. They actually experience development (a low bar to clear, but many of this genre fail there). I actually care about the characters, which I didn't expect to going into it. The art's nothing to write home about, but it isn't bad.

I know this is a meme, but I am actually reading it for the plot now (or rather the characters, as it's more on the slice-of-life side of things).

Don't go into this expecting anything more than what it is. Judging it as a ecchi-harem-rom-com it is legitimately very good.
