So, I think (hope) most of you realized what happened but just in case you didn't, I'll just explain it here instead of replying to every confused comment.
Yunho's cleaning out, came across the photo album and the "family" picture falls out. It's just the first of many surprises to come for him. But seeing it, specifically seeing Jaejoong, makes him remember the event that led to his sending Jae away.
They were in the midst of a particularly emotional lovemaking session and those three little words slipped out. There'll be more detail in the next chapter so I don't want to jump the shark but I will say that at the time, he was distracted and wasn't sure what he'd heard but later on when he had some time to himself, it kept nagging at him until he could no longer ignore or deny that it had happened. Shit just got real, as they say, and he called himself all kinds of a fool for not seeing it earlier. Or not admitting it, rather.
I don't know if people realize just how scary those 3 words can be. SC is about 75% based on [my] real life experiences, including that (but not how/when it happened!) except I was on the receiving end. It freaked my shit, to say the least, but I didn't run away. Instead I returned the words even though I knew that, at the time anyway, they weren't really true. Not yet. I think that makes me worse than Yunho, to be honest ><'
Anyway, it stewed inside him for a while and he tried to pretend it hadn't happened but when he could no longer do so... Well, you know what happens next. In his mind he did it to protect Jae more so than from his dedication to his dearly departed husband, even if he won't admit that to himself either.
So that's it. I can't say any more without spoiling the first page of the next chapter, which is a direct continuation from this. So be patient, I'll see you soon (three weeks thereabouts).
And if I could address just one more thing. I may offend some people but I'm beyond the point of caring, to be honest. If it makes me lose some readers, them's the breaks.
I write as much for myself as for you guys and I try to portray both characters as evenly as possible, however, I've been seeing a startling lack of compassion or understanding towards Yunho and a surplus of sympathy for Jae. I don't get it. Yes, Yunho did a shitty thing. He's human: we all do shitty, hurtful things. But it's not like he killed somebody or hurt Jae in such an unforgivable way that people should want Jae to fall for someone else. His actions didn't come from a place of hatred or malice, he really thought - stupidly so - that he was doing what was best for the both of them. Obviously he knows he made a huge mistake by now but that's life too. People have to make mistakes sometimes to see the big picture and learn from it.
And Jae is no saint, he is as responsible for his heartache as Yunho is.
There are no victims or villains in this fic, just two people in a complicated situation trying their best to muddle through it towards the ending that they think they want. And they will get that ending, regardless of what some people may want at this point. I can't please everybody and it was already written (figuratively) since the beginning. I can't make anyone care about him and it's disheartening to see all the anti-Yunho sentiments in the comments, it honestly made me feel like not finishing the fic at all, but I'm going to. I've come too far not to.
So I hope I haven't ruffled too many feathers but if I have... *shrugs* so be it.
I'll see you guys soon.
PS: Yunho's going to find a lot more things in that box, things that are going to unravel all the secrecy around him. I wonder what they might be...
