What would have happened if Hwarang Hansung and BTS V switched minds with each other? How would they survive in such different time periods? Will Jungkook be able to help them return back? (BTW, this fanfic involves character and details from the kdrama Hwarang, if u haven't seen it yet, it may be confusing to understand. I would suggest u watch it first, but its entirely up to you. ENJOY~
