In what way? I think it was okay. It could have focused more on the pharmaseutical aspect and medical stuff since that seemed important part but it sort of got sidelined at the end (Mr. Han mentioned to Prince Reok about something bad happening to Sangyul if he stopped taking his medicine but that never was adressed later and I thought he had already stopped after the "tissue" code..)
It could have shown more about the imperial family (Emperor especially). There were no mentions how he felt about the marriage or anything that was going on.. same with the brother/heir. Also the Empress getting same standing as Emperor never went anywhere or was that the point of allowing them to get married..
Also the Han family could have had more fleshed out story. The eldest got some time but then the shares thing didnt really go anywhere after that.. no real mention of the second brother either. And no mention at all about their mother/supposed wife. Is she alive or deceased at this point? If she was dead then why is the mistress still hidden.. so many questions. At least the illigimate son got a sort of closure.
On this note, it could have been explained better why Mr Han plotted what he did. He wanted the engangement for what deal? What was the deal they were negotiating. The druggie was just a cherry on top and wasnt part of the plan really.. Would also been chefs kiss to see how the spies could have been kicked out the palace (it must have been someone in inner court!)
Overall there could have been more characters. It really seemed like that main couple where the only people with any personality sometimes (well mr jung and empress were also quite impressionable). But other side characters? There werent many and didnt really leave any sort of impression.
But after ALL that being said I liked the plot. It was different even if the story had a fairytale vibe to it. Like how they were trying to create omega (and why omega and not an alpha?) and tried to trick Prince Reok. They lacked pheromones which is new to me in ABO story, and it doesnt seem they had heat/rut. Which is nice since that way their secondary gender wasnt really the driving force of their pairing but their own sincere feelings. It got little stale at the 30-40chapter mark but overall the flow was okay.
P.s.s. sorry for long comment and bad english grammar

I love the art but am I the only one who didn't like the plot/setting?
