Ok I've seen all remakes and the original. This remake needs a second season or more episodes (also longer then 30min per episode if possible) because it shows them getting married in a lavish wedding in previews and ending scenes. But this ending so far just shows her leaving for Okinawa and her husband being ok with it. So there has to be more of this particular remake. If this is all there this for this remake I will be highly disappointed.

Sorry again these are just my thoughts and personal perceptions on the different adaptations.
So in all the remakes they technically weren't divorced. Because yes she signed the divorce agreement 2 days after getting married but he NEVER signed it or dated it. So that also begs the question why get married again as if they were divorced? But I'm actuality they never were? Also that means neither party can get married to anyone else not can they date others or that's cheating.

Sidenote if there beaten path but...
Anytime there's a show and it has multiple remakes from different countries I always watch ALL remakes whether it's anime or live action. (Example... Boys over flowers, Playful kiss..) I watch as much as I can on Netflix, Hulu, Viki, YouTube and other sites where I can see any and all Asian dramas no matter what language they are in.
