how to speak "of course" in Korean?

worries Two weeks ago,I took a part-time job,because I think I have been a college student,I can not cost money from my parents,I have the ability to earn the money to cover my foodcost.But my parents do not agree to it,they thought I am too tired because our homework is the most in our college,I do not deny this,after two weeks'experience,I feel a little tired,but it also urges me to make full use of the rest time to study.My father still require me to give up the job.I just want to experience the feeling of growing up,but~~~~,I am helpless!

First notebook entry: Introducing myself I'm from China.This is the first year at the college.My major is English and I like Korea,so I'm learning the language of Korea.My dream is to be a diplomat.So I have strong interest in learning language.Happy to be a friend of you!
