Why I'd think Golden MV will be dropped at 17:00 or, if failing, at 19:30 GMT... a thread:

First of all, you need to keep in mind the schedule of Eroda Ferry: 11:00, 13:00, 14:00, 16:30 and 18:00; and that all the next times used will be according to ART (GMT-3) time zone.

Disclaimer: this could be just a series of coincidences and, of course, isn't 100% accurate because we don't know the specific time when many of these things happened. It's just a theory based on some facts that I don't fully expect to be true, but it's plausible, in my opinion.

Someone found Harry's photo for Golden at 14h (HSHQ posted it at 15h, though). I can't find the original tweet of the person who found it first, but I took a screenshot of the time I saved it.

Golden MV.
My initial thought for this was that they would drop the MV at 16:30ART (19:30GMT) because If you paid attention, you've noticed all the ferry's departing times were used to release every part of the promo for this MV, except for 16:30.

However, I now might lean to think they'll drop it at around 14:00 (17:00 GMT) as it was the only time that wasn't officially used and it's nearly sunset time in London tomorrow (16:44 GMT). I don't discard 16:30 (19:30) though; I'd expect it to be dropped either at 16:30 or 14h.

But , I guess we'll see when/if they give us a countdown...
If it ends being just a coincidence, it'll still be nice (and strange) that Eroda Ferry's schedule coincides with the timing of Golden promo in my time zone.

So, apparently I was right and Harry's brain is brilliant. I made a mistake on this thread, though. I said that 14h was the only timing not officially used, but 16:30 wasn't oficially used, either. However, I took the time they posted the dog video as around 15:20/16:30 because +

I couldn't check the exact time (that's why I said I didn't discard it, either, but would lean to think it'd be at 14h), I'll do it later just to confirm.
Just wanted to add this. Now, enjoy the countdown! #Golden
