Jackie, a small bear girl residing with her brothers, possesses an impulsive nature that drives her to devour all household sweets alone. This act sparks conflict with her siblings and leads her to flee home, setting the story in motion. During her absence, she crosses paths with Mindy, a young apprentice pastry chef. Jackie's profound love for sweets inspires her to pursue patissier training alongside Mindy at "Sweets Land," a confectionery shop operated by Mindy's grandmother. She seizes this fresh start, revealing her capacity for growth and emerging dedication.

The narrative centers Jackie in a challenge for Sweets Land as the village chief schemes to seize the establishment. Her journey unfolds with warmth and gentle melancholy, mirroring her emotional arc. Visually, she retains her small bear design and signature red overalls, consistent with her origins in the picture book series. Her development occurs solely within this self-contained story, with no documented expansions into other seasons, OVAs, or spin-offs.

Key relationships define her progression: tensions with her multiple older brothers and newfound bonds with Mindy and her grandmother during her patissier training shape her personal evolution.
