I stumbled into this anime at complete random, picking it out of a list sheerly because I thought the character designs were cute (and they are!) and I was pleasantly surprised how enjoyable it was. Characters are dynamic and the story is rather simple but enjoyable in its simplicity. Katarina is a delight and nothing elevates a harem like having a main protagonist where it actually makes sense that everyone likes them. Hell, she basically worked her ass off to make sure they did! It's not gonna change your life or anything but I imagine you'll have a fun ride on a light hearted bisexual harem romp.
