In a relationship that appears to be harmonious on the surface, Dan starts to have doubts about her lover when she has a vivid dream about being betrayed, which causes her to find an envelope that is addressed to Phuc. Despite the fact that Nguyen tells her that it is merely her imagination, the reality that he has been concealing is progressively revealed via even the most little of elements in his regular life, such as a peculiar odour and his growing unease.

As soon as Dan realises that the letter has not vanished but has been relocated, she realises that she has been tricked into believing something that is not true. The dream was never a prediction of what would happen in the future; rather, it was only a gentle awakening to a reality that had been existing quietly in the present for the entire time.
