Me iba a quejar de la frase pero me equivoqué al traducirla del coreano all inglés
This is what I say when my Korean friends try to speak to me in broken English
English is a difficult language to learn for Korean speakers, and vice versa. You should have some empathy as a Korean learner yourself.
Probably any language is hard for people to learn aside from their native language.
That's true, but Korean is especially difficult for us compared to most European languages. It's the same way for Korean people who learn English. The two have basically no linguistic relation, while other languages such as Romance or Germanic languages have a lot in common with English. It would be much easier for a Korean person to learn Japanese than English, because of the similar grammatical structure and the influence from Chinese on both languages.
