If the prospect of reading a (gay??????) scifi story about a bipolar jerk (Eve/Rat), a confusingly determined piece of paper (Shion), and bees coming out of people's necks appeals to you, then I can recommend it.
To start, there's nothing particularly bad about the premise, I mean having bees erupt from people's necks is equivalent of a disease that kills people in a horrifying way. It's silly and dumb, but most anime is and I just found myself laughing about it anyways.
The characters are decent at first, Shion being a levelheaded guy who just wants the best for his friends and Rat (oh god that name) is a cold, heartless guy. But then they don't really go anywhere. The character progress resets sporadically and you'll have to sit through the same scene 4 different times. This happens with many different scenes, such as: Rat and Shion fighting but then resolving it, Rat and Shion monologing about how much they saved each others life, and Rat and Inukashi having their spat among a bunch of other types.
If you found this manga because you heard about it's mains being the best couple evar, you'll be met with Rat tossing Shion around half the time like a 6-year old with a pinata bat. Rat kicks the crap out of Shion on several different occasions and professes his hatred for the guy. They kiss like twice, but then don't ever address it. They don't even address homosexuality at all. Yeaaah, it's a far stretch to call it romantic. There's a reason why it's not listed as Shounen-ai in the genre tags.
It's a waste of time as an action dsytopian scifi romance (?), because it doesnt know what it's going for and it keeps repeating itself, getting nowhere with the characters.
