jungkook is a high ranking docter/surgeon, he had just finished a heart surgery and transplant and he is on his way somewhere since he is taking a 15 minute break

While he's walking, he sees you, you are also a high ranking docter/surgeon, you and Jim are frenemies. Kind of like rivals since you are both competitive with eachother. And he smirks and comes up to you

"Guess what, I just did a huge heart surgery and transplant, beat that, moron" he smirks
