Y/N L/N's future was already planned out for her. She would meet with the matchmaker, be trained on all the duties of being a good wife, get married off to a man, and bear his sons. However, things go awry when she finds out that her thirteen-year-old brother will be conscripted into the army. Refusing to let any harm come to her brother, she disguises herself as a man and flees to bootcamp, where she meets Ping. Little does she know, she and Ping might be more similar than she thought.
