That was my point. Korean is something of an isolated language. Most languages have modern cousins, e.g., German and Dutch, any of the Scandinavian languages with one another, all of the Slavic Languages, most of the Romance languages except French. Manx and Erse. Hebrew and Aramaic and Arabic.
Spoken Korean did get mothered by Chinese long ago, but written Korean is very different from other Eastern languages. Chinese might have thousands of different symbols but Korean has 24. Plus the subject-object-verb order is a bit strange to me.
Some of the literal translations are funny. “His neck is dry” means he is thirsty.
Then there are the oddballs like Finish and Basque.
