Intro. Jungkook is your childhood friend and your first love. The first boy you kissed, the one who was always there at recess, the one who shared his lunch with you, he was your neighbor. There were 3 friends Jungkook, hoseok and you but with hoseok you didn't get along and Jungkook defended you from him. From one day to the next, Jungkook leaves the country and promises you that he will return and that they are going to get married together. Years go by and eventually he comes back but... There was only one problem: he came with his girlfriend. I think I had forgotten the promise he made to you, but it also changed something in you: now Hoseok became your best friend, they didn't fight anymore and that makes Jungkook jealous.
