I don't know if you guys will agree with this, but I am just going to go with what I think. But first, let us go through the evolution of BTS. We can then see how our boys have grown.
With their debut song No More Dream (this is personally my favorite song by them)
Now haven't these boys just evolved through the three years. They are so innocent. Or are they?
They planned this from the beginning now didn't they... I looked on the video myself, and if you go to 2:08 you will see it. Don't believe me? look for yourself!
Doesn't that just bother you?
So here I will say my theory because of this. Now I am sure some wont agree with me, because some people think that Jin died, and they have good logic behind it. My theory is just going on because of this screen shot on No More Dream. Lego
The boys didn't have any real dream, not with a girl, not with anyone. They wanted to live happily, that was basically it. To show that they tried to convince themselves AND others that it wouldn't happen, and that they are bulletproof, but once they see a girl and they start crushing on her they tried to deny it saying N.O. but they had given in and decided to confess to the girl, showing that they were just boys looking for love. After it had happened they started to date, but they didn't see each other often, causing the boys to say what they would want to do if they had just one day with the girl. The relationship then became in danger, considering it wasn't a real relationship nor was it going anywhere, and if the girl truly wanted to be with them then she needed to do something about it. So she had done something about it, and it caused the guys to realize that they had hormones going on for this girl, but she didn't back. They wanted her to them they what she wanted right there, but she decided to break up with them. Because of it, it caused a traumatic affect on the boys, and weeks later they realized that they loved her and that they needed her. they then ran away from the feelings, opening up again becoming a butterfly, and realized that they didn't need a girl, or really anyone except for themselves. They boys needed each other. Now you are probably wondering why I skipped Dope, well it is because if they didn't give into the feelings and such for the girl, non of this would've happened. In a parallel universe, where if they choose a different path, they would have been happier and just dope, and wouldn't have to run away from everything.
So there is my theory. Let me know what you guys think, even if you don't agree and want to stick to your own theory or someone else's.
