待我强大必将手刃负我之人
[dài wŏ qiáng dà bì jiāng shŏu rèn fù wŏ zhī rén]
Translated as 'Wait Till I Get Strong, Then I Shall Personally Punish Those Who Betrayed Me.' This suggests someone filled with ambition, anger, and perhaps desire for retribution. It shows that this user likely faced some significant betrayal in his past and has vowed revenge once they are powerful enough.
