Dw, Nathaniel isn't neglected, that guy has a followers beside him ready to fight and defend Nathaniel.
Also have you look at his clothes and hair??? His accessories??? Doesn't seem neglected, that guy has a beautiful garden, whereas MC tend his own garden so what neglections are we talking about?? He got all the care and everyone's attention, everyone worshipped him like some god even you and the other readers here                                            
                                                ????? Neglect comes in many forms lol. 
He IS neglected. By the king. It's literally in the manga, his chambers arent being visited because the king favors his concubine. And as the OFFICIAL husband, it is his responsibility to bear an heir. Without an heir, his standing isnt secure. It's all politics when it comes to all these. That's like, the point of these harem nonsense. Why you see in other manga how the official / first wife would harass the concubine / second wife and their offspring. Power comes from being favoured by the king.                                            
Also he signed up for that, stop acting like he's a fragile bird, he's not pure, he had those nasty followers and sending a mirror gift that basically said that Christ (mc) is basically nothing and ugly compared to him. His garden are beautifully designed, clothes are top notch, getting the best hair care, and most of all, LOVE BY MANY PEOPLE. HE LITERALLY ALMOST HAD IT ALL. HE DID NOT MARRY ML FOR LOVE. HE KNEW THAT HE MARRIED INTO A POLY RELATIONSHIP. HE BLAMED IT ALL TO MC
                                                He's just a gold digger in royal attire, he's living the best life, his status were threatened by Christ
Have you properly read the updates??? "I AM THE ONE WHO WILL BEAR HIS MAJESTY'S CHILD" He's basically saying that he doesn't give two flying f4cks about ML's love and attention, HE WANTED TO USE A CHILD TO SECURE HIS STATUS IN THE PALACE                                            
                                                Did you even read my response. Or are you an alt of the potato guy because the two of you are spouting the same thing lol. 
Lets get things straight : 
1. I never treated him as a fragile bird, dk where you got that from, idrc. 
2. If you understood what I said, you know what I'm pertaining to. Stop being willfully obtuse. The king is not doing his marital duty. Like I said, POWER is having the KING'S FAVOR. If the concubine bears heir over the queen, their influence and power is as good as gone. People will curry favor to the concubine, instead of the queen. Crown Prince, will be informally the concubine's son. And if there are factions backing the two (which usually there are) the concubine's faction will gain more power in the country. That's why the queen is acting out, and why his rancid actions towards the mc makes sense. This is literally explained in the manga, and it's not like the manga is complex... If you don't understand that, this conversation is over. 
3. The conversation is not about love, stop making that the focal point and start understanding the manga instead. If you people can understand spoilers, surely, you can understand the manga.                                            
                                                I have read the updates properly, have YOU understood my response? 
"Use a child to secure his status in the palace" Exactly?? That's literally the goal lol. Power is EVERYTHING in the political setting. If you understand that, i cant fathom why you don't understand him acting out when MC is threatening is position.                                            

		
If there’s gonna be polygamous, at least the husband needs to love all of his wives, not neglect one to another.
