Jungkook is your mom's best friend's eldest son who is of the same age as yours..you both study in the same college but since he's quiet and shy, you both have barely talked with each other over these years and its awkward..while in lift both your moms chit chat while you both just stand there awkwardly not knowing what to do

one day you were alone at house when you heard a knock on your door, you opened and saw it was jungkook

"my family isn't at home and I don't have the keys with me..can i stay here till the time they come back?"

he asked politely, you could see the poor guy didn't have any idea his family would forget to leave the keys for him and since it was raining outside you couldn't do anything else..
