What do you think about William's YouTube live and what he said about Izaya? I remember you writing that you cannot figure out how they could make this work. Pains me to admit it, but guess you were right.
I just watched it because of your ask. Or I should say I skipped through it to the parts I found interesting.
So what I gather (correct me if he addresses it at another point and I skipped over it) is that they were together for a year, then Izaya tried to relocate to Spain or stay there for longer than a vacation, and was denied visa. They then had to sit down and talk and it sounds like they realised that unless William moved back to Japan, they are stuck in this limbo of being apart and missing each other and therefore ended it. They decided to cut off contact completely, which makes total sense, especially of there are still feelings. William doesn't sound like he's over it and lives in the world where one day he'll go back to Japan and then they might get back together because they are star crossed lovers. That might be true, sure. Sounds like he hasn't really accepted yet that it's over. Or not. I think I remember William announcing a while ago that he was going to move back to Japan, but now he's still in Barcelona, so seems like that didn't happen.
Now, personal opinion, because you asked for it: I get why they broke up. And I also get why he can't let go of it completely. I was once stuck in a situation like this for 10+ years. Basically my first real relationship was like this for over ten years. And it sucks, However, there is also something that I didn't realise back then and that's the simple fact that if you REALLY wanted to change the situation, you could. I am not saying it's easy or fair to both sides and that sacrifices won't have to be made. But if these two really wanted to be together, ultimately, one of them could quit their job and move in with the other in Japan. They could get married and get Izaya the visa that way. There are more options, but I hope you get what I mean. However, it doesn't look like either if them was willing to sacrifice their job (temporarily) or the life they have built somewhere for being with each other. And that's fine and understandable, I am bot blaming anyone. I am just saying, that this is also a fact.
Now, William might be right of course and one day, he might go back to Japan and they run into each other and get their third chance. If they both want that, I hope they'll get it. Or either of them might have moved on at that point. or they get together and find out they have changed so much as people that they don't work anymore. Who knows. So for now, sadly for us – and them most of all – it wounds like they are not together anymore and William is brokenhearted about it and hoping for a third chance at some undefined point on the future, while it also doesn't seem like either of them is actively doing anything to make that come true. Or maybe they are, we don't know. I wish them both the best and the romantic in me really hopes they'll get it together.
