Jaeshin has some powers to extend or decrease someone's lifespan
Wasn't he literally punished for using those powers?
Yes lol. He is an underworld being so he can live with Nok wherever so doesn't matter if Nok lives or dies they'll always be tgt
It will come up soon (but there was some mention about it already) , and the problem is that Jaeshin belongs to the afterworld, but Nok is just a simple human who needs to reincarnate as a human. So he can't just take Nok with him as Nok will reincarnate (and will forget Jaeshin, just like his mother forgot him, as she was also a human)
I doubt there will be sequels about the reincarnations so maybe the author will end the story on a 'wherever we live we belong together happily ever after' note. The story is going fast in season 2 so it's not that far we'll find out what's their ending
Does that mean Nok will have to die to be with Jaeshin in the afterworld? Or is there a possibility Jaeshin will give up is immortality to be with Nok in the actual world?
