I mean, I understand y he doesn’t love him. He was treated like the Duke’s personal prostitute (w/o even the courtesy of getting paid lmao). He was forced into this. He had a girlfriend and I wouldn’t have been surprised if he wasn’t even into men. Compliancy is what this is. He simply adapted to the situation he was in. If he had the choice, he’d b with his girlfriend, get married and have kids…but he never got the chance to even make a choice. So yeah I’m glad the author is basically saying brother doesn’t loved him, and he never will.
I have to agree with the author. This story isn’t about love. It is about obsession and fear. I think as it goes along we tend to forget the reason Ilíc is in this position. He is a murder. He isn’t a good person that something bad happened to. He has accepted his fate and he is by making the best of his choices. He is for sure lucky Sayan didn’t get tired or bored with him.

Hey guys, in the novel Ilic actually does have a dream that Sayan will die, and even though he doesn't die in the novel itself, it is heavily implied that he will die later on because he is super sick. Also, Ilic never actually tells him that he "loves" him, as that was added in the webtoon. In fact, it is made pretty clear that even though Ilic understands they are a couple and cares for him, he doesn't love him the same way Sayan does, like true love. On Twitter, someone asked the author to please tell us if Ilic actually loves Sayan in the end and she said she would "leave it to our imagination," but that is what the novel implies, that he doesn't love him the way Sayan wants. Then in another tweet someone begged her to please just say he loves him and she literally said "no" xD, meaning she won't confirm it but it is understood that he doesn't love him. I was reading another forum discussing the ending of this novel and honestly everyone feels the exact same way xD In fact, if you go back and read this webtoon with that mindset, you'll realize it really is like that.
