A burned-out office worker and a ghost child who doesn't understand why adults destroy themselves, that's the entire show, and it needs nothing else. The ghost's solution to everything is "go home," delivered with a whine that somehow becomes the most honest advice anyone's given her in years. Twelve episodes of someone finally being told to stop, by the last person who should care, and actually listening.

Fushihara is a corporate slave who stays glued to her office computer, working overtime long after her coworkers have gone home. One night near midnight, she hears a small voice telling her to leave. It belongs to a little ghost girl said to haunt the building, who worries about Fushihara's health and wants her to go home. The ghost tries to scare her out of the office and even brings her refreshments, but her cuteness backfires: Fushihara would rather stay and keep working. The result is a gentle supernatural comedy about everyday life, as the time the two spend together steadily brings warmth and happiness into Fushihara's overworked days.
