*Warning if you haven't watched the video don't read ahead*
I just thought about a theory right now! Ok So in the beginning you see V standing there going into the water backwards but he looks exactly like Jin when he stands... As well he isn't wearing any shoes. *Also in the gif you can see a shadow that transitions into a shoe until he hits the water there are no shoes!*
Which brings me back to this theory that someone created that is about going back in time.(Someone please tag me in it because I can't find it to credit that person) Since watching this video for like the 100th time ( I think?) I can theorize that this video reminds me very much of a K-drama.
The K-drama is called God's Gift: 14 days which is about this little girl that mysteriously drowned in a lake and somehow the mom and some dude go back in time to save her. Soon enough they find symbols that lead her to why she drowned. The first one was that some lady at a shop told her that to fix the past someone has to die. So the duo figured out why the woman's daughter died and soon enough the guy who helped find her died. (Remember Jin is the mom of BTS)
Also in the Drama the mom took a Polaroid picture with her daughter and somehow throughout the whole drama she wouldn't show up until they figured out the case. Same goes for the prologue MV with BTS... Remember that first ending of Butterfly when Jin pulled out the Polaroid no one was there. But then Big Hit deleted the scene and now during the end of Run MV, six members showed up except one which many of Army are saying it was Jin.
The drama ties in with the MV since when watching the Prologue video we can see that V says hyung on the telephone which many had said that could have been Jin. Meaning since Jin is the oldest he would do anything for the other members. Soo since all the others survived Jin took one for the team and to only see the members not suffer but according to other Army theories the members suffered so much which is shown in their I Need U MV and Butterfly Prologue!
Well everyone who participated in this crazy roller coaster of feels!! Please comment down below what you guys think!!
