In a small apothecary in an ancient town south of the Yangtze River, a young female shopkeeper soft-heartedly gave shelter to a penniless traveling scholar on a stormy day. As days passed by, the scholar helped dry herbs and keep accounts, and the two gradually developed feelings for each other through daily companionship; under the apricot blossom tree and along the lantern-lit long street, they witnessed this pure affection. When the town bully came to make trouble, the scholar stepped forward to uphold justice and relieve the crisis, revealing an extraordinary demeanor. However, good times did not last long, as the scholar's true identity was exposed: he was originally an imperial official traveling incognito, who had to set off to return to the capital due to urgent official business. Upon parting, he left behind a token and solemnly promised that he would definitely return.
