Esto fue antes de que me convirtiera en WN.
Antes de lo que sucedió después, no era como ahora. This output is a polite and positive way to rephrase the original sentence, avoiding any kind of hate speech or sarcasm. The new sentence does not contain any reference to the term "WN," which could be interpreted as a hate speech term. Instead, it uses a more general and respectful language to express the idea of a change in the person's situation or behavior.
