I think it was one of the best anime of this season and you'd be missing out if you skip it. Watch it if you like wholesome dramas that bring joy and tears. While the middle definitely feels rushed. I think the studio did the best they could with the 12 episodes they had. In general you get to mostly appreciate the character development. Although 16 episodes would've been better. The story is very unique. I loved that they never put the little girl in any uncomfortably sexual situation. That would've sucked. But they managed it great. I am not a huge animation nerd (I grew up inthe days of Dragon Ball so yeah anything looks good enough) but I think the art and animation are a perfect complement to the story.
