1. Traffic competition caused by similar video types: Fat girls from rural areas turned into online celebrities and attracted nearly 10 million fans by cooking delicious food. However, Xiaofeng's food is more popular with the old people and has been widely praised. This may make the fat girl worry that Xiaofeng's traffic will exceed her, and their relationship will become tense.

2. Conflicts occurred during filming and failed to reconcile in time: According to relevant information, Xiaofeng and Pangmei may have had conflicts during filming before, but they did not apologize to each other, which led to the failure to ease the relationship.

The above is only speculation, and the specific reasons and circumstances may only be clear to the parties themselves. Contradictions in interpersonal relationships are complex and diverse, everyone has his own position and viewpoint, and only the parties can truly understand the whole picture of the relationship.
