Soobin's death was the result of an assassination plot from an enemy nation. Soobin's nation and the enemy nation is the same two that were at war during the duration of the fic and ultimately destroyed each other.

As for Kai and Soobin, I would say yes. Soobin would have landed in Elysium due to his heritage and his divine blessing. I think they would meet on accident - maybe one day Kai takes a little stroll around the fields the same time Soobin is getting away from the frenzied party he was dragged in to (as he was in life). They would meet again in the rolling fields. Soobin would be in shock - wondering how much time had passed and why Kai still looked so young. Kai would look at his old friend with guilt - he had outgrown the prince, Soobin still retaining his young glow of early adulthood. Eventually, they would embrace with tears of happiness and sorrow towards each other. Soobin doesn't blame Kai for his death - he never did.

mhhhhhh this is quite the hard question - took me quite a while to think about it so my answer might sound incomplete - im sorry :(

for there to be angst, i feel one must know the central emotional conflict of their story. what do each characters personalities and behaviours effect the conflict? are they different or are they the same? is that a good thing? or if its just one person - what are they battling with mentally?

for example, in exchaning heart, the main emotional conflict was that Soobin fell in love too late and having to reconcile with losing that part of himself. Hanahaki is a pretty straight forward trope, but its implementation was used to give greater impact to the main conflict. There is LITERALLY no hope for Soobin's feelings to be reciprocated, but he still struggles to give up something so precious to him, so central to who he was.

since i usually use third pov but just for one character, i usually like to use their mental turmoil to bleed into the real world. like, what we experience really depends on out emotions and this will also effect what we notice and dont notice. so, when writing, emotional states will dictate how the environment is described.

i also like to sprinkle in some irony, because if you think about it, comedies and tradgies are the same, its the matter of tone that differenciates it. why do you think shakespear was so good at it? a situation that makes you laugh in a normal situation can turn sour quickly with the wrong emotions. miscommunication, misunderstandings, missed timing.

i hope this helps? trying to write down my messy thoughts is difficult so i hope this makes sense! you can always dm me <3

i kinda always knew that the ending would be Kai ending up in Elysium and the two of them reuniting, i would punch MYSELF if Kai was cast into tartarus.

However, I did have a different plan for the entire REST of the plot. My other draft was outlined and all before i quickly changed it to the current edition. It starts with Kai already in the underworld, but because he never got a proper burial, has to wander the banks of the Stxy for 100 years. It would be more about Kai coming to terms with his circumstances and eventually death, while still fearing his placement because of his 'divine punishment'. Hades/Yeonjun would learn for the first time the fear of being judged in death. But I got stuck trying to make it interesting when the setting was so bleak and they do nothing but wander. I did have a few, really raw lines in that draft tho, which i really do want to use sometime in the future
