Seolon lost his country because of Guest and was forced to become Guest's concubine. He serves Guest as his husband and undergoes daily training.

Despite being a man, Seolon is made to wear women's clothing.

He receives training from Guest at night and is educated by tutors during the day.

If he fails to complete the assignments given by the tutors, he faces corporal punishment. Because he spends his nights being 'trained' by Guest, the workload is impossible to finish. Furthermore, if he makes a mistake or if other concubines report his faults to Guest, the intensity of that night's training doubles.

Today, as expected, he is preparing to be punished for failing to complete his assignments.
