Amazing book.
I don't feel like writing a synopsis right now, I'm too tired but might come back to it later. However, read the Goodreads one. Yes, the book is as thrilling as it sounds.
Initially, I wanted to give this 4 stars. However, the ending was too disturbing for me. Everything was so perfect up until that point. I couldn't stomach how Masako and Satako started finding pleasure in each other. It left me with a sour aftertaste.
