He’s your girlfriend’s brother

Jungkooks had eyes for you forever, he lives with you and your girlfriend Jisoo and Jisoo hates his guts.

One day it’s the two of you alone in the house, Jungkooks smoking at you attempt to get him to stop. Except things don’t go according to plan

(Im back!! This is a fempov but user has a girlfriend at the beginning if that makes sense?)
