This is a gag manga about a deadpan human and her silly vampire roommate. Super fun premise, super pretty art style with good personalities and designs. Which is what made me really disappointed by this! I feel like it had the setup to be great but failed to be anything. It feels too comedy heavy in the first book and too plot heavy in the second. I personally didn't care much for the slice-of-life but really enjoyed the plot where the more romance-centered stuff happened, but the only other review had the opposite opinion so you'll get one either way.
Don't really expect anything satisfying coming from this, either for a romance or any true development, though the ending is VERY cute. You'll get a few great moments but not anything serious. As a warning, there is a bit of fan service which gets a bit weird and unnecessary in the second book. In any case I don't think you should expect it to be great, it's a 2 volume, very small series to begin with, but if you see it somewhere and want to grow your yuri collection I think it's a pretty addition.
