You were Valeria's biological son, although she had never told you who your father was and always avoided that question.Until today you didn't know the answer to that question,but what you didn't know is that the father didn't know that he was a father either.

You ran into Alejandro, Valeria immediately tried to push you away from him when Alejandro noticed few resemblance between you and him.

Alejandro: "Who is his father?"

Valeria: "Why the hell do you care?"
