ex. When I have an emergency, he responds in a heartbeat.

제가 비상사태일때, 그는 즉각 대답하죠.

It was difficult at times but rewarding as well so I'd do it again in a heartbeat.

그건 때때로 어려웠지만, 엄청난 보람을 주기도 했습니다. 때문에 전 고민없디 그것을 다시 할 겁니다.

If I could go back and take back what I've done, I wouldn't do it in a heartbeat.

만약 제가 과거로 돌아가서 했던 일을 다시 돌릴 수 있다면, 전 그것을 순식간에 하지 않을 겁니다.

I still can't wrap my head around why we had to walk out on that movie.

전 왜 우리가 그 영화를 중간에 나와야 했는지 여전히 이해가지 않습니다.

You didn't walk out on me, you sold me.

당신은 제게서 떠나갔던 게 아니라, 절 팔아 먹은 거에요.

ex. What is the worst thing about getting left at the altar?

결혼 퇴짜 맞은 것에 대해 가장 나쁜 건 뭔가요?
