5 needed to calculate an average
Pretty much same concept. Both are collection of stories about undead who don't behave like your average zombie. In both they retain their humanity in their new life, though they still have to overcome the problem of rotting etc. The limited lifespan and body decay seem to limit the chances for romance, but somehow it still a common theme in both manga. If you read one and want to read more of the same, check the other manga.
