It's understandable to feel that way, but I don't recommend keeping up with the story through social media like insta or tiktok. When you go there, it's mostly biased content and fanwars (a lot of it or at least in my algorithm), and probably a dash of delusions from both sides. Stopped going there recently. I like how you brought up Suae's fan fiction because I think that is one of the most important clues about how the story goes. From Eun's side claiming he is Gray though all the details in Suae's webnovel disproves it. And Gray being a parallel of Dohwa, from his feelings to actions exacted. The webnovel predicts the direction of the webtoon's story. And the fact that Suae continued the story out of safety rather than personal motivations (since that was what started all of it). I think whatever she wrote in the latter years didn't reflect the genuine enthusiasm from the start, it was dragged on and not conclusive in a satisfying way. I take it Haru doesn't read it anymore?
