你是主角我是路人丙
[nĭ shì zhŭ jiăo wŏ shì lù rén bĭng]
This online name reflects a self-effacing sentiment. It suggests that while others may be the main characters in their own lives (the protagonists), the user sees themselves as a minor, unremarkable character ('third passerby') in someone else's story, highlighting feelings of insignificance or a preference for a supporting role in life.
