So... This is my first review so go easy on me.
This anime is basically about 4 couples, all of them constituted by one human (a teenage boy in the case) and one supernatural creature (that goes from a kind of yellow and superfluffy bear to cyclope twins, being the twins married with the same guy). It shows their daily life basis as a married couple, the "wifes" taking care of the house and sometimes even doing more romantic stuff like going on a date.
Story: I give it a 6, although I enjoyed it I recognize that the story is plain, there's no drama or what so ever, it's a pretty white and simple slice of life I would say.
Art: I give it a 6 again, the characters are cute, especially the creatures, but , again, simple. There's nothing wrong about it being simple but there's nothing that you could call eye catching.
Sound: A 7, I liked the score, it wans't bad, especially the ending, through out the 12 episodes there was not even a single time I skipped the ending, it was fun and it goes pretty well with the whole anime.
Character: It's a 7, again, some of them are cute, pretty adorable but... I mean, they are a bunch of guys that married a bunch of creatures, they have moments when they are really adorable but sometimes they can also be a little way too boring.
Enjoyment: It's a 8, despite all I really enjoyed it, it was different, it's not an anime for all the otaku community to watch but it's worth watching, for the right people.
Overall: Its a 7, I liked it, it's not the worst anime I ever watched, also not the best but I still had a really good time watching it. If you want a little romance, a little yaoi, a small slife of life and a ending you can dance to, this is a good shot.
This is only my opinion so don't be mad if you don't agree. Also, english is not my mother language so sorry if I made any mistake.
