At the Xia family's birthday banquet, a young man brings two cans of agarwood fragments as a congratulatory gift. His girlfriend's cousin smashes the cans in public, mocking them as "broken wood scraps," and the crowd joins in the jeering. When the girlfriend steps up to defend him, the prospective father-in-law blames the guest for lacking a sense of propriety without asking about the reason, making the atmosphere awkward. Amid the dispute, a senior in the incense art rushes over upon smelling the fragrance and recognizes it as rare aged material, causing everyone's attitude to shift accordingly. The young man remains neither humble nor pushy, asking only for a word of respect and an apology. After investigating the whole story, the elders deal severely with the discourteous person and awaken everyone, showing that gifts have a price, while sincerity and respect are priceless. Two cans of agarwood and a birthday banquet reveal that what gets misjudged is not just the gift, but human hearts.
