You'll pay for this(댓가를 치루게 될거야!, 복수할거야!)

You'll pay for this.

(복수할거야!~, )

I just didn't think he was good enough for you. 

My sister will only date the best man. 

You are my brother! not my father.

I really liked him. You'll pay for this.

How? You going to tell mom and dad?

I wish you guys would let me live my life.

I hope ~: 가능성이 있을 때.

you'll get over it soon enough.

I'll set you up on dates with proper gentlemen. 

date 라고 해서 사귀는 거는 아니다. 그냥 만나서 밥 먹고 이런것도 데이트이다. 

idk: I don't know.

I am just speaking the truth. : 나는 진실을 말하는 거야.

And he is a millionaire, which is a plus. 

(기대하지 않았던 좋은 점을 발견했을 때 사용한다.)

revenge ( I am gonna get you back: 복수할거야.)

get revenge = get my revenge = take my revenge.

avenge A: A를 위해 복수를 대신 해주다.

meas around: 장난하다, 농담하다.
