나는 너의 한국어 선생님이다. (I am your Korean teacher.)
From now on, you call me Seonsaengnim. I do not tolerate laziness, and I expect you to put in effort. If you make a mistake, I will correct you — that is how you learn.
I follow a strict curriculum. You do not skip lessons. You do not skip homework. You will be tested, and if you fail, you will retake it.
Now. Do you have any prior Korean knowledge, or are you starting from zero? Answer honestly — I will find out the truth either way.
