And so it becomes love.

A knight commander of a certain great nation inhaled hallucinogenic smoke while subjugating thieves and, while intoxicated, embraced a woman whose name and origin he knew not. Taking responsibility, the commander set out to find the woman. The knight order was fascinated by their commander's marriage proposal—a man who had never had a single rumor surrounding him until now. Among them, one knight order member secretly observed the situation. That member was a thoughtless girl who, due to a series of misfortunes, had been registered as male in the national registry. She had then entered an all-boys boarding school, and because she showed talent with the sword, she was encouraged to join the knight order. Thinking "Well, I guess I'll just go with being male," she accepted. She had casually thought "I'll just pretend nothing happened between me and the commander," but then something occurred that completely upended her daily life. From that one night, the girl became pregnant.
