I think they r talking about the fact that dokja after making a deal with secretive Plotter goes to another dimension as in the 1864th turn when he comes back it's already been 3 yrs on earth so his teammates all kind of believe he's dead and joonghyuk especially is distraught w/o his wifey. Idk if this is what they r talking about but this is what's gonna happen next.
Maybe it'll take 3 years for us to reach there, lol. It's actually pretty far. There's demon king selection arc, then Dokja getting isekaid without his companions' consent arc, then coming back after 3 years arc (where all his companions get to know the truth), then war of saints and demons arc where YJH angrily attacks KDJ and HSY thinks he's seriously gonna kill him..

the divorce arc- I NEEDDDD SPOILERSSS PLEASEEE
Everyone's talking about it but not one comment I have read spoiled it yet. PLZZZZ SOMEONE ANYONEE
