The development between Kyon and Lucaon is probably one of the best, and my favourite thing to read. It just felt so natural while reading, like it wasn't forcefully expressed that the feelings were developing for both of them, but you could just feel and see it through their actions.
To be honest, I didn't start loving Royal Servant right off the bat and even thought that it was boring/ not that interesting but damn, I think this is going into my Top 5 BL webtoons.
Sigh..... really wished there was more closure with some other elements though (Ryan and Christopher, Edward, etc. Maybe even some more about Sihan and Karis). However, I actually do enjoy the ending with Kyon and Lucaon. I don't know if I can say it's 100% satisfying, but I do think that it was a really good ending and can't exactly think of a better way to end it while not making it seem way too ideal/ unrealistic. Definitely hoping for a whole bunch of extras though
