okay, several notes on this. firs of, where did you get it from that they were the love of each other's life? i just wanna know your references on this one, apart from the fact that probably at the time, they thought that, hence they got married. which then i guess also begs the question of what that even means.

next, you're a little wonky on the timeline, which i don't blame you for. in june, jk tells taehyung he and aerin broke up one and a half years ago, and during that conversation and also later in the story he hints at the fact that they had problems long before then. if you want my author intel on this (which i don't know if jeongguk is actually gonna open up about this detail) it's that they had "problems" pretty much from the point they got married onwards (if you're wondering if this was about the baby thing, yes it was about the baby thing. if you're wondering if it was about jeongguk being in the public eye, yes it was.)

that aside, i do really get what you're saying, though. i think one thing you can say about rep jk is that boy moves relatively quickly. i mean, he got married at age 20 and he already had a few relationships before that. i don't know how much you picked up on it in the story – i feel like this new chapter touches upon that a little bit – but his relationship with aerin and how it fell apart did a number on him and it definitely left its mark.
about him moving on and healing: that man sat his ass down in therapy. he'd be a whole different person if he hadn't. he'd also be a slightly different person if he continued going, but that's another story
