From a young age, Shinoda was extremely unhappy due to difficult circumstances within her family: her father passed away early, leaving her mother alone to take care of all the children's education, while she had to help her mother earn money to support the family. Because of this, she always harbored the dream of making a lot of money to help her mother live a more comfortable life until she reached adulthood. The job she chose to serve this purpose was to work as a maid in a wealthy merchant's family. In order to earn a lot of money from him, she had to sacrifice a lot, especially from her young and fair body. She always dressed provocatively, arousing his lust and leading him to rape her, and sooner or later, she would have his entire fortune. It was a cunning plan of an ambitious maid full of ambition.
