I said it then. I say it now. Them trips opened Jk's eyes again and those feelings he had for Jimin years ago, came right back. He has that similar tattoo yes, but he wasn't able to have a proper relationship with her, if he had one, due to being enlisted, while he was nurturing his relationship with Jimin and depending on his through hard times and grew very close to him, even intimately closer. They were isolated in a place and only had each other and in a place where they had to suppress emotions, attraction, feelings and sit on them for 2 years. It's like they couldn't wait to get home to travel and its very possible them feelings they were holding onto, just came out, because of all the romantic stuff they were doing together. And I think when he came home, he probably did try a relationship with her, which explains showing up at airports traveling to the same place, maybe even tried to bottle up anything he was feeling for Jimin, but now, being back together, working every day, doing promotions for AYS, I bet that old flame was def not gone, but reignited. So I do think he ended things with her. Maybe even to explore with Jimin. I guess we will never know, but I would not be surprised, cause of how bold Jimin is being toward Jk. I also don't think this would be JIkook's first round at this either. Maybe friends, with a little flirting on the side right now and just enjoying everything.
I think they've done this rodeo before more than once. Their lives are very extraordinary so it makes sense their relationships are also the same. Months ago, I said that it would be interesting how JK's relationship would survive the challenge of the world tour but it seems it didn't even survive the prep for it.
