Raised by her father, a high-ranking military officer, Benio is educated, independent, and unafraid to challenge societal expectations.

Benio’s life takes a dramatic turn when her father arranges her engagement to Shinobu Ijuin, a lieutenant in the Imperial Japanese Army, without her consent.

The plot intertwines personal struggles with broader historical events, such as Japan’s involvement in World War I and the societal tensions of the era.
