In alternate history, in 2026, modern South Korea is a constitutional monarchy. The royal family is in name only, the chaebols are as rich as the country, and the class gap is bottomless.
Sung Hee-joo is the shady illegitimate daughter of the top chaebol Sung Group. She has single-handedly built a top-notch beauty empire and has a business worth hundreds of billions. She has top-notch looks and a ruthless mind, but she will always be stepped down by the upper class because of her status as a commoner. In order to break free from the shackles of her birth, she set her sights on the nation's beloved, noble but powerless and moneyless King Li Li'an.
Dressed in a red suit, she made a high-profile appearance at the royal dinner, and used a brand show that gained popularity to overpower all the nobles and family members who looked down upon her. What she wants is never love, but a contractual marriage in exchange for the royal status of "Mrs. Maharaja" and truly rise to the top.
Li Li'an, the second son of the royal family, has a dignified and cold temperament. He is burdened by the shackles of the royal family. He is popular among the people, but he is trapped in the financial crisis of the royal family and is restricted everywhere. He originally disdained the illegitimate daughter of a plutocrat who was full of copper odor, but he had to accept the olive branch she offered.
The chaebol has money but no status, and the royal family has fame but no capital.
In a contractual marriage where each gets what he wants, two people trapped in the cage of identity go from using each other, testing and pulling, to falling deeply in love. Amidst royal intrigues, internal fighting among plutocrats, public opinion turmoil, and class strife, they become each other's only salvation.
She uses capital as a blade to tear down class barriers; he uses his royal status as a shield to protect her with all his edge.
In modern Seoul, the 21st century king and his chaebol wife staged an extremely tumultuous struggle for superiority and love.
