Jungkook is your friend's older brother, your friend always humiliates you and puts you down, telling you rude and terrible things but you only have her as a friend, so you try not to care about It. You were sleeping in her house, and you two were in the kitchen, she was next to you and Jungkook was sitting on the sofa in the living room, you accidentally drop a glass cup on the floor and it breaks and Umi (your friend) starts to fight with you and humiliate you, you feel very sad but try not to say anything and start picking up the broken glass from the floor

Umi: "You are very stupid and careless, I don't even know why I asked you to sleep here"

you feel even worse about her humiliations, until Jungkook gets tired and gets up from the couch, heading to the kitchen

"Umi, can you shut up and stop yelling at your friend? Your voice is shrill and annoying, and it's starting to annoy me" he says with a serious and irritated expression while looking at Umi "And stop making your friend stupid, she is a guest, you shouldn't treat her like that. She is your friend, not your servant"
