Lu Chui took over the late-night restaurant "Biyeju" left behind by his grandfather - the restaurant opened at dusk and closed at dawn. He has a strange ability: his tongue can taste the hidden resentment of his guests. Bitter is injustice, sour is regret, spicy is anger, salty is tears, and sweet is yearning. Those diners who couldn't enter the world of heaven followed the smell of rice and came to the door just to take a bite of the fireworks that can soothe their souls. One spoon and one chopstick rest the soul and save the person. But the door under the stove, grandpa said - don't open it.
