Also, I noticed in the Proof concept photos that the white light shining on each member's face leaks onto them from the door they entered, and this light gives the message, "this door will always be left ajar for you to return." The members returned in Merry Go Round with the wear and tear and growth they gained during the journey from that gap; a message was given that they will be happy as long as they are together, regardless of time and space, but the doors are still infinite and referring to endless new chapters.
The doors evolve along with the members, and each door represents an era of BTS. BTS leaves their own mark in the rooms inside these doors, both as solos and as a group. The room behind each door is the memories in the BTS universe.
Jimin and Jin both see a horse which represents freedom, breaking free of the things tying us down and those who oppress us but they are looking at each other because they are each others freedom. Only when they are together do they feel they can find answers
