I had such high expectation for this book but alas, it is mid. So mid. 

The book reads a lot like a slice of life. In that there is no plot. Instead, the narrative is very much driven by the characters, leaving the novel feels at time aimless. Certain revelations about the characters' relationships do not have the emotional punch it deserves and comes off at very out of nowhere since it outrights contradicts things said earlier in the story, especially since there's no indication that the narrator is unreliable. Hence, it just comes off as odd. 

Of course, this may very well be a me problem instead of the book since the typical three acts structure is more of a norm in Western storytelling rather than Japanese.
