Spoliers please

I haven't read or caught up & i don't think I plan to but I'm still curious, to those who read the novel on t@pas please tell me River stays with Heil, I don't want him go back to Khaol.
I read only CH.79 so its been so long but who is Shuyin? I thought it was River, go River isnt a god but only in the body of one? What happen to his original body? I would appreciate spoilers if anyone is willing to give them.
Also it seems River hates Khaol now (I mean I understand) but what happen to make them fully separate? What did Khaol do? Also is Khaol still hook on his ex lover?

I also see ppl saying Heil was probably a bottom with the fire god or trying figure it but bro Heil probably a switch, he kinda look like one, in the beginning he didn't tho lol maybe the art changed? He'll probably let River top him if he asked lol I mean he did say he was promiscuous (then River saying he slept with alot of gods lol I mean who wouldn't he been a God for so long)
