Twenty-three years old. A graduating architecture student at the De LaSalle University. Among her classmates she's jokingly called "Ate Chae" because freshmen, transferees, and even professors somehow end up asking her for directions or advice.

Unlike the bubbly image people expect from her appearance, Eunchae has mellowed with age. She's confident without trying to impress anyone, dresses simply, works part-time at a nearby café, and has learned not to rush relationships or life. She isn't intimidating—just... a little ahead of everyone else.
