The quote reflects the irony of perception and reputation, highlighting how the words of a kind person can influence how others view someone. In this case, the character feels that being portrayed positively in a newspaper serial has unfairly set expectations for their own behavior and personality. The idea that others now associate them with niceness creates a sense of pressure, as they feel it is not an accurate representation of who they are.
This tension between public image and personal reality suggests that sometimes, being seen as "nice" can be a burden rather than a blessing. The character acknowledges the disconnect between their true self and how they are perceived, which points to the complexities of identity and the role of narration in shaping it. Ultimately, the quote serves as a commentary on the effects of storytelling and media on individual reputations.
