I get what you're saying, but I also get the ML's point of view. political and business marriages are such complicated things. You can't force yourself to sleep with someone you don't like but,you still have a responsibility you cannot reject. If it were me and I was married off to someone I don't even like, i think I'd be keeping my distance too. It's not Nathaniel's fault either. They're all victims of their circumstances. Thank God we live in an age where our preference matters.
Do you know if Allen is still sleeping with Nathaniel or what? Cause if his purpose in marrying Nathaniel was for baby, and Nathaniel apparently has a difficult time conceiving, why does he have to still be married to Allen?
I genuinely wish he could get out and find some real partner. Do you have spoilers perhaps? I made a lengthy post asking for spoilers and my rant. Asking cause Chris says that Nathaniel is not pregnant YET, so implications that he and Allen are still sleeping together? Or only on Nathaniel’s heat cycle?
I feel like it’s vague, but that’s just me. Perhaps novel readers know more in detail. Honestly I felt bad for Nathaniel the most in this story, just seeing him be upset that his husband is visiting the consort more and having sex, nah not cool at all.
Of course it is kinda the same thing on Chris’s side, he has to endure his husband still being with Nathaniel and potentially another concubine. Honestly, I don’t fuck with the ML.

Honestly speaking I hate the ml so much like how can you leave your official husband. I get it you like the mc but he is totally disregarding Nathaniel. If you see it from the villainess manhwa pov it's the same as the "crown prince" Leaving the official engaged "villainess" for the pure clumsy "female lead" and how is the mc this dense also the story plot feels so forced. The story feels like the ml is just here for the mc's body full of lust rather than love. I feel bad for Nathaniel cause it feels like since he can't give birth he was left alone as useless and the stupid ml doesn't think about Nathaniel's feeling at all I wish Nathaniel divorces the ml and gets a new partner
