I came for the yuri, but stayed for what turned out to be some surprisingly solid science fiction. I was expecting wacky robot hijinks, but this series actually has some pretty clever takes on classic sci fi questions like "do robot feelings count?" and "why even have humanoid robots?" (I especially enjoyed the answer to this question).
The way the robot works is very thought out and logical (well, maybe except for the super hacking and some of the more sentimental things, but I can live with that), a lot more grounded than I expected from a series about a high school girl falling in love with a robot.
Another pleasant surprise was the researcher's attitudes. In nearly every other story about androids there would be a lot of mustache twirling and drama about keeping the robot secret or designing it for ulterior purposes, but these guys are more like parents to her, and care for her both as a machine and a person at the same time. That feels refreshing, and makes sense. It also makes totally sense that when their robot falls in love, they see it as an interesting engineering challenge instead of going all "love bad! We tampered in God's domain!".
The only thing I didn't really like was how abruptly it goes from them finally dating again and them getting married, in the span of a single panel. That was a bit jarring.
