Seeing that the person who was riding the MTB is not in the photo, it seems like the photo was taken some time later.
I did not see the person who was blocking the passage on the opposite side of the bike rack at that time. If the photo was taken some time after, that part would be different from the situation at that time.
Since you mentioned it was your first time using the Gyeongui-Jung Central Line, when boarding the train, it's common to move inward first to secure space for other people to board, rather than immediately docking the bike.
I remember the person in question was holding the bike until the door closed, trying to set it up. It was not at all stacked on one side like in the photo. While the person who entered first was docking the bike, their companion was waiting in the back, and after docking against the wall, the companion moved inward and started setting up two bikes.
I remember the person was holding the bike while stacking them until the train door closed, and their companion was waiting right next to them.
After some time, the second companion moved inward and the MTB rider entered the train. Looking at the blue section on the floor in the photo, if bikes are lined up against the wall, they would occupy more than half the passage due to the bike's length. The MTB rider could not move all the way inward because the person in question and their companion were standing in front, so they entered diagonally from the end.
From my position, the right wall side did not have enough space due to the already docked bikes, and on the left side, the MTB and its rider were standing, so there was almost no space to enter. I even tried to enter by standing the bike vertically, but there was no space. And there was also not enough time.
You clearly said there was plenty of space and no problem with passage or boarding, but in reality, there was not enough space.
And I was in front of the entrance before boarding, yielded for you to board first, and also told you that you should move further in. So it seems a bit strange that you didn't know I was there. I think you might not have heard me because you were focused on docking the bike.
At that time, with only my front wheel on the train and the screen door open, the train door began to close, so I had to back away. In the dangerous situation, the train departed without me boarding.
If it was your first time taking the subway with a bike, I think it's understandable that this could happen. However, next time, since there could be people boarding after you, if you move inward first when boarding, it would be more convenient for everyone.
