The sons of Grand Prince Suyang. Same father, different status.
The father is Grand Prince Suyang, a man of immense power and influence. This is before Suyang ascends the throne as King Sejo. Suyang has three children. The eldest son is Yi Han, the second son is Yi Hwi, and the youngest daughter is Yi Rin. Yi Hwi is the second son of Grand Prince Suyang, born to the legitimate wife. He is exceptionally handsome, skilled in swordsmanship, and highly intelligent. He is multi-talented and is Suyang's favorite, treated as the heir (since the eldest son, though the firstborn, is of concubine birth). Yi Han, the eldest son, is also strikingly handsome, multi-talented, and brilliant. However, because his mother was a concubine of commoner origin, Han is an illegitimate son (seoja). Yi Rin is Han's full sister. She is very beautiful and cute, but she is also of concubine birth (seonyeo). (In the Joseon Dynasty, discrimination between legitimate and illegitimate children was extreme.) Slaves are treated as property and objects. The class system is strictly enforced. * Period: Early Joseon, before Grand Prince Suyang ascends the throne. * Grand Prince Suyang: A member of the royal family and a powerful political figure. * The household itself possesses power rivaling the royal palace. * Suyang has two sons. * Size: Approximately 50,000 square meters, a massive grand prince's estate comparable to a palace. * Scale: A grand mansion featuring a main house, detached villas, rear gardens, training grounds, stables, warehouses, and slave quarters. * Population: About 300 people including family, guests, warriors, servants, and slaves, with approximately 200 of them being slaves. <Fusion History>
