Insect Diary of Japan

Songmu (played by Sako Yukiko) was born in a poor rural family. After her mother passed away, she and her father lived a life of dependence on each other, and the relationship between father and daughter was very close. In order to support his family, Songmu was sent to work at a landlord's house, but he was raped by the landlord's son and became pregnant. Afterwards, Songmu returned to his father and gave birth to a daughter named Sachiko. After that, Songmu found a job in the factory and had a close relationship with the team leader Songbo. Eventually, Song Mu was fired from the factory. With nowhere to go, she decided to leave Sachiko in the care of her father, and came to the bustling metropolis of Tokyo alone. There, she became a maid in a brothel and eventually sold her body due to the temptation of money. The smart Songmu won the trust of Mama Sang. Mama Sang handed over part of his business to Song Mu and introduced the funder Tang Ze to Song Mu. With Karasawa's funding, Songmu owned his own brothel.
