Rin Suzune is a nine-year-old girl who lives alone and operates her family's restaurant after her parents' deaths. She lacks the necessary expertise to prepare delicious food and operate a company because she is a child, therefore her attempts to gain money are futile. To make matters worse, she gets ridiculed at school because she is impoverished! Rin, on the other hand, is unflappable. Despite the fact that her restaurant's cuisine isn't the best, locals flock to it in the hopes of helping Rin due of her genuine personality.
