It does appear that to get to Cuenca that a trip to Seoul Korea is necessary. My wife is a native of Seoul yet a naturalized US citizen of about 25 years. The problem is that she doesn't have a copy of her birth certificate. According to the Korean consolate only a family member can obtain it and all my wifes family is in the US, so in order to qualify for a visa we gotta fly to Korea to get a birth certificate. I love Seoul but I hadn't planned on this added expense. If only there was a simpler way.
