Some correction:
Line 1: he had a different body at first but it rotted and died, even if you are immortal, your body still ages and the mind is the only thing being „alive“, so he had to leave his first body and get a new one.
Line 4: correct, it didn’t work because he was gaslighting himself into believing he was in love, while he wasn’t.
Line 10-14: yep!!! He is trying the ritual again after only some time again, because he thinks that maybe now the Uke is genuinely fooled and likes him now. I think he wanted to alter the ritual this time with something new too.
I think the black hair priest can only become primus if he kills the blond guy too, that’s why he was searching for so long and wanted to start the ritual now again.
Thanks for the corrections!
Uke was human child and meet ml but ml used a fake body. Uke tried to create a bond with black hair seme but failed and trying to prove he did love black seme he hooked up with ml.
That faild and bc of a fight uke almost die and bc ml wanted uke to live reveal who they really where and made a bon an became mates. That cut the ties with black hair seme.
Black hair seme on the meantime is trying to become a god but he can't unless the have there mate aka uke and are trying the ritual again. That is why they need him back at the mansion and they are using his insecurities to lure him.
Meanwhile ml is trying to kill black hair and maybe blond too.
And the last part looks like black hair was a childe that wanted revenge on vampires ended becoming one and tried to create a family for himself but due to society stigma the wife and the baby died and maybe because of that he wants to kill ml
