Would've made a decent book of perhaps half the length, were the translation cleaned up.
The length I blame on the author: the book was extremely repetitive. The translation was odd, including pet peeves of mine such as translating units from metric to Imperial without considering usage (e.g. the original (I assume) "30 degrees Celsius" translated to "86 degrees Fahrenheit" when complaining about a hot day. Nobody talks about the first day of the summer when the temperature exceeds 86 degrees.) as well as more substantial oddities where half the characters were walking around with childlike expressions.
The core of each of the 4 stories were fine, and I was surprised that the author included slight twists to the stories. TBH, after the clumsy beginning, it was more than I was expecting. This left the book good enough for me to feel bad about abandoning it. So I ended up not regretting finishing the book, but regretting borrowing it.
