We're on day 3 out of 7 and updates keep coming, of course there will be more. As long as there's financial support to the project, that is :p
What comes to the plot...
(spoiler)
I have a feeling it will be about embracing change and living in the present. Their old relationship is finally dead, so they can figure each other out anew and get together as adults.
I'm making a bet we will see Mikko burning at least one of his stupid journals - his obsession with them makes them a perfect Chekhov's gun. He said he didn't bring any physical ones with him but he often lies with a straight face, so ;P
Also I am extremely curious to learn more about his relationship with Joonas. I'll go ahead and make another bet that it fell apart simply because Joonas wasn't Arvo. >:3
