Nina, a young girl starting her first job as a personal assistant in a family home that feels unfamiliar to her, hits her lowest point when an important pair of glasses belonging to her aunt's child breaks, triggering scolding, guilt, and days filled with tears. From this incident, Nina learns to face criticism, adjust to her new environment, gradually build relationships with her family, and discover strength through mistakes and life's pressures, ultimately growing into a more mature, confident person who understands that life's cracks are not the end but a beginning to learn, take responsibility, and rise stronger, with a touch of light romance and support from those around her.
