Some of the premises of this show tackles themes relevant to real life; the conflicts that the characters face are conflicts that we could be facing in real life. It is a show about the burden of duty. Duty and piety for your family and country is esteemed to be the norm and is what drives the characters' emotions and conflicts. It goes to the point that it feels too overdone - to the point it gives me the idea that Japanese people consider piety and duty for one's family more importantly than other people in the world. It makes a conclusion to the ultimate conflict of the plot by asserting Yuri solves all of the problems.
If you don't appreciate Yuri, like how I don't, you can still enjoy how the characters of this show do face some realistic conflicts that we could face in real life and how it's resolved relatively convincingly, not completely convincing, but to some extent, convincing. There are a few plot holes but they can be ignored for the sake of enjoyment.
The characters are all likeable and full of emotion. They are all driven by some kind of underlying emotion except for the Euphie. This aspect of Euphie plays a role in the story.
