For example in the case of Anita, the Countess of Falcon, you see her plotting starts early and the novel does talk a lot about it. But at the climax of the event, Roy handles it super cleanly and doesn't even leave a trace for something dramatic to drag on. Even the Countess of Wales, during the party break arc, it didn't go on for too long and show all sorts of plotting and petty schemes.
The "drop of a hat" thing might not necessarily apply since it seems like Emperor fell for Wakaba pretty quickly, but it doesn't really matter. Even though from the beginning I wasn't rooting for him, to see all the hype that the author built up based on the premise of the "Kaburagi Group's heir" and yet he loves someone else is still quite disappointing haha. Although he's written so pathetically it's alright he doesn't end up with her. I would like some more hype built around the family of the probable male lead though, but I think it's coming.
First of all, I think ML's self-control is praiseworthy. The premise of the story is that their body type experiences uncontrollable sexual urges, and yet ML holds himself and reins him in every time because he doesn't want to hurt MC. The hallucinations MC sees, that's not ML's fault at all. Like one of the characters said, "he can stop himself from f*cking you but he can't stop himself from wanting to" (in maybe not exact words).
Next is ML's jealousy, and honestly he's not really a jealous character at all, especially compared to typical MLs of other stories. He doesn't stop MC from getting close to his friends and building relationships with others of any gender, including a friendship with his goddess or play flirting with others. The thing about the dislocating his arm was to use pain to help MC break free from the hallucination he was trapped in and to warn him to be careful in future situations. The decisive action is more due to his character than jealousy; he would've acted the same for another comrade even if he didn't love them.
Lastly is the thing about the subconscious. The reason he always went is mostly because he enjoys the peace and calmness of the place, as he said, and not because he was trying to manipulate MC's feelings. He went for the environment, but the things that happen there were mostly the initiative of the MC. At that point, ML is heartbroken that MC won't be able to remember anything that occurred, and due to his physique none of this can happen in real life, so he uses pain as an anchor point so MC can feel that even in that fake reality Heine is there.
However, although I've defended ML a lot, after they have reciprocatory feelings I'm kinda unsatisfied. Like I know he's controlled himself so much that everything starts to break loose and he really can't stop himself, but he's still way too rough lmao, even if it turns out that MC likes it rough.
Also, I really can't dislike Ning Xiao. Yes, it was pretty cruel of him, but in his position, I would also be upset and want nothing to do with the person. How he chooses to live his life is none of my concern, especially since he makes it pretty clear to his partners that there are no feelings involved on his end. It's not like he ever treated anyone forcefully, even after he becomes interested in MC (yet at least).
One reviewer disliked the story's attitude of rape, and they're not entirely incorrect. Of course in the real world r*pe is r*pe and it's not okay. Personally, I didn't really mind what occurred in the novel, mainly because in the end r*pe didn't actually happen. Regardless, I don't think it's a key part of the story since it was the concern of a side character. In the story, it's more the general ambiance is light and humorous, not that the author wanted to treat this topic very lightly. Edit: The whole topic is treated perhaps too humorously and too lightly. Personally, I still enjoy this story, but definitely be careful if this is a sensitive topic for you.
