Mon-Mon moves to the city to learn fashion design from her idol, but her new job is babysitting a toddler with impossible powers while pretending nothing is wrong. The comedy lives in her desperately genuine effort to keep up, to be professional, to learn something, while everything around her rewrites the rules of physics every single day. She can't win because she's fighting a battle nobody else acknowledges, and the show finds something tender in that exhaustion, a country girl's kindness tested not by cruelty but by the simple chaos of caring for something beyond her control.
Mon-Mon arrives in the city with starry eyes and a single ambition: to learn fashion design from the legendary Mrs. Kano. Landing a live-in position as a nanny seems like the perfect opportunity, even if the household is unconventional. Mrs. Kano is brilliant but scattered. Her husband is a hapless novelist. And their infant daughter PePe is... something else entirely. At first, Mon-Mon chalks up the strangeness to city life she doesn't understand. But toys moving on their own, animals following impossible commands, and reality bending around a giggling baby become harder to ignore. PePe's innocent chaos transforms each day into unpredictable mayhem that Mon-Mon, despite her genuine sweetness and tireless work ethic, cannot contain or comprehend. Just when homesickness overwhelms her and she's ready to abandon her dream, PePe's affection proves stronger than any logic. The psychic infant won't let her leave. Trapped between her aspirations and supernatural babysitting, Mon-Mon discovers that sometimes the life you didn't plan becomes exactly what you needed.
