Traduko - Rumana-Angla - Fata mea, dacă vezi mesajul ăsta, lasă-l

Wouldn't "as this is a great villain" be better like "as this one's a great villain"?

I like your suggestion, koneko! supashi-bo (?)

I am not so happy about that "my daughter" in the begining. It can be something like "sys", because the one who addresses these words can be also a friend. "fata mea" is a very informal expression in Romanian (an annoying from my point of view), I doubt this is a mother talking to her daughter.

And I would have said "scoundrel" instead of "hoţ", but I guess villain works too.

Yeah, me neither, I don't really find it most appropriate - "my daughter" - but I don't like "sis" either... Isn't it way too informal, like "dude", kind of used amongst young people (girls) of the same age? It seems to me that this piece of advice is given by someone who's got some more life experience, is probably elder than his/her collocutor, and worries about him/her. It's only an interpretation. What about "sweetheart"?

Yeah, I believe that's better, I did not have any better idea in that moment... "sweatheart" is more proper, I believe.
