Alright, I'm very interested in how Nero's romances work! I remember that you said that the relationship with Marazhai is supposed to be the main thing, but I wonder if that has changed? Do they have a "sharing is caring" situation with Kibellah, a poly romance, a complicated jealous relationship, or something else? And how do all three of them feel about it?

Complicated question as well as their love triangle, and it just requires the wall of text… Thank you for this one!! 🖤✨

Kibellah and Marazhai hate each other for sure, Nero blindly loves and trusts them both, but differently, making things complicated for everyone.

From Marazhai he needs brutal lust and the ecstasy of pain that kills his own nerves with overstimulation, making him completely numb to the pain. The head becomes quiet too, no thoughts, no voices, just void and the feeling of freedom. And after all the tortures Marazhai inflicts on him, Nero faints and actually resting physically and mentally when his heart barely beating.
Nero accepted his role in Marazhai’s dominance game, assuming that was the Dark Eldar’s love language. All he has to do is keeping Marazhai happy and Nero gets what he wants. Though, Marazhai doesn’t mind sharing his living toy with anyone, knowing that his pet will eventually come back to him like a moth to the light. He only becomes angry and jealous if his pet neglects feast for long.
Things might have been different if Rogue Trader’s mental state in Commorragh had been better.

Marazhai cannot satisfy Nero’s need for physical contact, such as tender hugs and kisses, so Nero comes to Kibellah.

In his relationship with Kibellah, he plays a dominant role where he can’t properly relax in the moments after their intimacy, overthinking that Kibellah only sleeps with him because he is her Domin and her body and will belong to him. He can’t talk to her openly about it because he doesn’t know how, given her initial devotion to his title. Nero tests and observes her faith in the Undying One and her feelings for him, waiting what will undermine first.
Until then, he is just happy to finally have someone he cares about. He feels nothing but pure love for her anyway. He is willing to do whatever his Princess of the Void wants, even if it means sewing his eyes or spilling his blood for her rites. And Kibellah feels the same mutual feelings, but she is confused herself. Besides, she’s definitely not happy about being forced into poly romance with a xeno…
Kibellah feels confused in this love triangle, protecting her Domin from whom he doesn’t want to be protected and she can’t do anything about it. Hopelessly watching her Domin and filthy xeno hide in the captain’s chamber. Heartbreaking for both mon'keigh…
