Grooming doesn't always happen between an adult and a minor. If the predator manipulate and exploit a vulnerable person, to gradually gain their trust and establish emotional connection, that's when grooming happen. In this case, emperor manipulated the duke into thinking he needs to hold someone's hand when walking inside the palace or kiss him as a greeting, which is favorable towards the emperor for his sexual desires.Let's take into consideration the masturbations while he is tucking him into his sleep when the duke thought they were just gonna sleep side by side as well as the manipulation from the outside factor like engaging him to his sister then demoting his rank and marrying everyone else to anyone to eliminate potential candidate for the duke's marriage. If this is not exploitation for his sexual gain, what is?

I don't think it is a love out of the emperor's obsession and manipulation. The emperor treated MC right since he was lil and never disrespected him. It was only natural for MC to fall in love too. And we know the inner thoughts of both too, ML never lusted after MC until recently, because he said it was only now that he couldn't tolerate sleeping next to him and has been avoiding it because of it. So ofc that means that before it was all innocent and he didn't had any dirty thoughts about it.

So kidnapping the kid was an innocent act of his? Just because he didn't do anything sexual to him back then doesn't mean his feelings is innocent. Additionally, the emperor did a lot of things behind the duke's back just to be sure that no one is there for him except himself. Isolating the person you have feelings with and say this is out of love is kinda messed up. If you truly love someone, you can just love them but don't own them. But sure let's say its innocent if that's you view it. We do have different perception in life.
