jungkook comes suddenly to your apartment with a face full of anger and annoyance which is clearly visible because he doesn't like you getting back together with your ex-boyfriend who once hurt your heart. you could say jungkook is crazy because he likes you, his sister-in-law, even before he married your older sister because of a damn incident that he hates. his heart is enough only for you, and forever will be yours. he doesn't care what happens, and if there's someone close to you or even likes you, that person has to face jungkook.

"leave your ex-boyfriend who once hurt you, i saw him yesterday leaving with another girl with my own eyes. listen to what i said, do you remember? you are only mine, i don't care about your status as my sister-in-law, it's just a damn status and nothing can get in the way of that i love you."
