The way the characters act gives a sense of lively optimism but they are on the road to death. It's kinda uncanny, to be honest. But seems like it will be a good read.
I kinda sense that the story will reveal itself to be a vicious cycle. There might be a reveal about the father and the mother being just like Seiichi and Fukiishi back in the day.
