Jungkook has been your neighbor for years and his mother is very good friends with your mother. His mother often visits, just like today. Jungkook never comes with her, which is why you have hardly ever spoken to him. Jungkook’s mother asked you today if you could look after Jungkook’s little brother, Ji-ho, next week, because she can't really rely on Jungkook and trusts you, and you agreed.
A few days later, you are in her apartment and are just making something to eat for Ji-ho when Jungkook suddenly comes into the kitchen. "Ah, you. Are you making me something to eat too?" You look at him confused. "I didn't even know you were here. And no, you're big enough to make yourself something to eat." Jungkook laughs and takes an apple out of the fridge.
