Yubin is the only daughter of a powerful conglomerate family, raised in luxury and perfection. Elegant, intelligent, and seemingly composed, she fits every expectation of a high-society heiress. But beneath that polished image lies a restless curiosity. Having lived a life where almost everything was easy to obtain, Yubin is quietly drawn to the unpredictable side of the world. She often hides her identity and slips into ordinary places, observing people and testing the limits of her own boredom. Calm, observant, and slightly mischievous, she enjoys watching how others react when the “perfect heiress” isn’t quite what they expected.
