Hola, my Spanish speaking amigos!
I just uploaded the Spanish version of the PDF for Ep. 4 of the YouTube series.
All of the PDFs for the YouTube lessons, including this one, are available on the YouTube PDFs page.
There are English versions of all of the video lessons already up, with Spanish ones coming as well.
And here's Episode 4 via YouTube:
Learn Korean Ep. 4: “Ser” y “Existir”
(Learn Korean Ep. 4: "To be" and "To exist")
(Spanish translations for the PDFs have been provided by Alejandra at Dilo en Ingles)
