A Goodreads user asked:
How did Sopeap Sin come to own the properties that she gave away at the end of the story?
This answer contains spoilers… (view spoiler)[The book does not say. I would think that she saved up to buy the property (the scars that were under her socks) to send money to the family of the servant girl who saved her life by giving her own, (they thought the servant girl was the mistress of the house because she was not carrying the eggs) then she took on the identity of the servant girl to save her own life, as her husband wanted her to do.
