The chapters are shockingly concise, and it's unclear whether it's due to the original writing or translation, but they consist mainly of disconnected thoughts. Conversations often consist of simple replies like "Yes," lacking depth and substance.
Additionally, the translation quality is subpar; numerous chapters appear to have been未经仔细校对, riddled with grammatical errors.
