Synopsis：Thanks to an equal-opportunity scholarship, reserved but resilient Go Yuna enters Korea International High, a school reserved for the top one percent. Overnight, her mother’s remarriage turns her into the live-in stepsister of Woo Seungho, the cold, arrogant king of the school’s elite “Platinum” tier. She’s always been judged for being poor; he’s adored for being untouchable. Under the same roof and constantly at odds, a risky and forbidden romance slowly ignites between two people from entirely different worlds.
