Xia Youran, an independent coffee roaster with extraordinary taste talent, runs a small shop called "Morning Coffee" in Chengnan Old Street. The beans she roasts can present a flavor level that ordinary people cannot capture. With her obsession with coffee and her suddenly awakened food system, she has won a group of loyal customers deep in the alley.
Sumani, the daughter of the chain coffee group "Blue Coast Coffee", uses insidious methods to expand her territory and targets independent shops on this street. She first offered a high price for the purchase but was rejected, and then used despicable means such as maliciously lowering prices, cutting off supplies, and forging negative reviews to try to force Xia Youran to close down.
Facing the encirclement and suppression by the capital giants, Xia Youran's stubbornness was completely ignited. With the help of the gourmet food system and her innate sense of taste, she constantly breaks through the limits in coffee bean roasting, hand brewing techniques, and creative special blends. A coffee war about aroma and dignity has quietly begun in the old street.
