nope, the main actor is completely japanese. I was surprised too when I heard him speaking in Korean. It was so good (I am a fan of him and I rarely heard him speaking in another language than japanese and a little bit of english)

The doctor said that his case is very rare, so rather than trying to make his personality become 1, the treatment is to prioritize his life. Even if monday comes out as a single personality after the surgery, I doubt the doctor can do anything about it since they doesn't know what kind of treatment to do and also monday isn't some criminal or having violence tendencies that can be dangerous to the society that needs to be gone. Moreover, the doctor doesn't know which is his main personality (Ichinose is the only one who notice it, and it solely because of his scratching habit)

Also I kind of notice something when monday brought the signed consent form. It has 7 signs, even though it only have 1 name slot, unlike the consent form at the earlier of the movie, which has 7 name slots. I think it also indicates monday wish to bring back all of the personalities, even though I'm pretty sure that monday was the one who signed all of them lol. And his treatment consent form is always being renew every month (got this bits of info from the earlier scene too), so if monday is truly the only one who comes out after the surgery, he can simply stop the treatment and lead the life that he want.

Well that's only my two-cents about the plot, though

They made the ending kind of open, so everyone can have their own interpretation XD

I don't see the point for monday/tuesday to continue pretending to be the other personalities, though. When monday gave the new doctor the signed form to do the surgery and treatment, the doctor said that even he doesn't know how the result will be, whether the personality will become 1 or going back to 7 or maybe even worse. Also, as for the traits, monday/ tuesday maybe can learn and pretend to be the others, but as for the skills, i think it will be kind of hard unless the personality has merged with them (for example painting).
If you saw the credit, there are several post-it notes being shown (which I guess from the present times as they were talking about the car and other things)

I think they continue the treatment with the new doctor and going back to being 7 (looking at all of the new post-it notes and how they can communicate with each other better than before)

That's actually one of my concern too..
Like they keep postponing the production, meanwhile Fandy and Patrick keeps having their moments growing as an actor. The idea of having the old casts to act again seems getting far and far as time goes by. I do feel happy for their success tbh, but in the same time, seeing the possibility of this movie to become true getting harder makes me sad.
