Our Hating Game (COMPLETED)
Jin was Jungkook's brother's best friend. They started as friends, but they got entangled in one person who started their hatred for each other.
That was two years ago. Now that they met again in the military. Jin is Jungkook's superior, but Jungkook refuses to back down, despite the rank and superiority.
Until the tension between them reached its boiling point, and Jungkook started doubting that maybe this is not just other competition and dislike. Maybe it was more than that.
