Jeon JoonHee has always been a tough girl. So it wasn't really a surprise when she and the famous idol Kim Taehyung came out that they were together. Her being the "guy" in the relationship, of course. Only there was one problem. Her brother, Jeon Jungkook, also likes Taehyung. And he's in the same band as her TaeTae.
