Source is from episode 3.

There is a lot that can be said about this series in general, but to start with, I just want to talk about the anime. I went into this series blind and absolutely loved it. It is a great depiction of how a single dad that is forced to suddenly figure out how to care for a young child will struggle. I especially liked that it showed the compromises that must be made in the dad's career in order to care for the child. Japan's infamous work culture does not mesh well with parenthood, especially as a single parent.

Overall, the anime is a tremendously wholesome experience full of overcoming parental challenges, making new friends, and father-daughter bonding. If you want to keep your image of this series wholesome, then stop reading here.

I warned you, now I will be discussing the story in the manga that goes beyond the anime.
