别担心我不是好人
[bié dān xīn wŏ bù shì hăo rén]
Translated directly it would be 'Don't worry; I'm not a good person,' possibly implying rebelliousness or non-conformity in a somewhat humorous or ironic fashion. Alternatively, it might hint at an acknowledgment of flaws or mischief without necessarily being malevolent. It invites others not to hold high expectations or judge based on conventional standards.
