Most affective computing research treats emotion as a static property of text, focusing on the writer's sentiment while overlooking the reader's perspective. This approach ignores how individual personalities lead to diverse emotional appraisals of the same event. Although role-playing Large Language Models (LLMs) attempt to simulate such nuanced reactions, they often suffer from "personality illusion'' -- relying on surface-level stereotypes rather than authentic cognitive logic. A critical bottleneck is the absence of ground-truth human data to link personality traits to emotional shifts. To bridge the gap, we introduce Persona-E2 (Persona-Event2Emotion), a large-scale dataset grounded in annotated MBTI and Big Five traits to capture reader-based emotional variations across news, social media, and life narratives. Extensive experiments reveal that state-of-the-art LLMs struggle to capture precise appraisal shifts, particularly in social media domains. Crucially, we find that personality information significantly improves comprehension, with the Big Five traits alleviating "personality illusion.'

Table 1: A unified comparison of emotion-annotated datasets across three sources: News, Social Media, and Life Experience. Note: OV: Open vocabulary.
Figure 2: Hierarchical composition of the Persona-E 2 dataset. The sunburst chart illustrates three levels from inner to outer: original data sources, three primary domains, and fine-grained semantic subcategories. Note: Text Length: Short (0–30), Medium (30–100), Long (100–300).
Figure 3: Comparison of emotion distributions between Writers and Readers showing the percentage distribution of seven emotions across sources . Note: IUTB, ASK stand for r/iusedtobelieve and RandomActsofKindness.
Figure 4: Top- K emotion distribution across BFI clusters. The heatmap shows the average vote share (%) of the k -th most frequent emotion per event.
Table 2: Personality-based Top-1 agreement analysis. Top: Comparison of In-Group ( Agrin ) and Out-Group ( Agrout ) agreement levels ( N controlled). Bottom: Mean BFI traits for clusters. Note: Open., Cons., Extra., Agree., and Neuro. represent the Big Five traits; N denotes the number of annotators.
Figure 5: Affective transition matrices between General Writer and Reader. Red boxes highlight: (a) high resonance in News, (b) negative bias in Social Media, and (c) positive shift in Life Experience. Note: Negative: disgust, fear, anger, sadness; Positive: surprise, joy.
