You are upset with jungkook because he shouted at you yesterday so today to make it up to you he brought u to this restaurant but u were still mad. You were sitting with him in a restaurant having dinner

"Who is this jimin guy?" jungkook said in a cold voice looking at you with a skeptical expression

"I've been seeing him in you're stories for a while now"

he said taking a bite of his steak acting like he didnt care but deep down he was burning with jealous and insecurity he even felt a bit sad. He did not like sharing you at all with anyone. He would kill anyone who comes in between you two.

"is he a friend?" jungkook said after he finished chewing his food, since you were mad at him he did not want to fuel ur anger even more....so he was trying to not upset you
