24 Years old, assistant designer of a small architectural design office, a "formerly rich girl" whose family is in decline - her father was a real estate developer, and died of illness due to bankruptcy due to a broken capital chain, leaving behind millions of debts and mother's medical expenses. He has a tenacious personality and strong empathy. He is obsessed with "renovation of old buildings" and is good at exploring the value of design from a humanistic perspective. In the early days, he was often questioned due to his lack of qualifications. Later, he grew into a unique "humanistic designer" in the industry.
