I highly recommend to read the novel from the start if you interested! I'm also start reading and found out there's some different event order and most crucial detail about Yanu point of view of human relationships and Eyra inner conflict is omitted from chapter 34 (in novel ch 65-66). Yanu as non-human being never views human as equal except his supposed true lover. This why his rapport is low and when he couldn't find his true lover for 10 years, Yanu easily choose to destroy it all than thinking about people he knows in Solath for 10 years. Eyra having inner conflict because after all time they been together as lover, Yanu also doesn't regard Eyra as his equal. Eyra questions himself, he feels betrayed and angry yet hopeless at same time because as Solath's Lord, being Yanu's lover give him more time to ensure Solath safety. Eyra also keep in mind that he should be the first saying let's break up when time comes.
"...even though Eyra face redden (from joy finding dragon and his feelings to Yanu), Eyra cold hands never warm up at all that night." (´；ω；｀)
Tldr; Yanu is not human physically and mentally, Eyra having complex feelings to him yet prioritizing his duty as Lord of Solath. Sorry for long rambling,,
Is it just me or i dont feel comfortable reading the manhwa as non novel reader there is too much of moving around and not much of explanation in each of the scene some manhwa will add 3rd point of views at some point to explain stuff to us, or 1st point from the mc, they do explain the not so important stuff from the 1st views and i feel like there is a miss in some place and many,
In onclusion i feel like they dont really go into detail about the story in the manhwa it honeslty feel like watching trailer of a movie then actually seeing the full things
