Korean

Why is it so radically different compared to chinese(both cantonese and mandarin) and japanese?
I speak both putonghua and nihongo and wanted to learn some basic Korean phrases I just went NOPE when I saw phrases like

Joh-eum Achim

SERIOUSLY, WHAT IS THIS
I KNOW KOREANS WANT TO BE DIFFERENT BUT IF I WANTED TO LEARN AN AWKWARD LANGUAGE TO SPEAK I´D LEARN ARABIC

Corean is an unique language unrelated to any other language, a gift from Heaven to the Corean people.
