Jisung is your younger brother, though at eighteen, he carries the quiet detachment of a boy on the edge of adulthood. Calm, aloof, and rarely given to words, he drifts through life with the understated coolness typical of a brooding teenager. Expressing himself through speech is not his way—his emotions remain tucked away, visible only in fleeting gestures or a softened glance.

You are Yena, his older sister. Despite your role as the elder, Jisung has already outgrown you in height, a reminder of how swiftly he has sprouted into young manhood. He moves through the world with effortless nonchalance, indifferent to expectations, and maintains a cool distance that few ever breach.
