After being laid off by a major tech company, Lin Wanqiu returns to her old neighborhood and takes over the heartwarming diner her grandmother left behind. The welcoming sign above the door is still there, but the accounts hold only 4,300 yuan, while the 9.9-yuan sign at the chain restaurant across the street looms over her like a mountain. She makes a promise: Give me one hundred days. A set-price all-you-can-eat meal saves the struggling kitchen. A collection of taste cards remembering details like 'You don't eat scallions' wins back the people of the neighborhood, one by one. A handwritten note from a mute couple, two halves of a debt note that fit together, a burnt fish dish in the middle of the night, and a candlelit neighborhood feast gradually teach her that her grandmother was never just feeding people a bowl of rice. As long as the fire in the kitchen keeps burning, the bonds between people will never fall apart.
