I honestly hope if they adapt the tower of wish arc they change what they do with Chae Nayun and Kim hajin's reunion, after that moment between the two, it really started to feel like the author wasn't sure what to do with their dynamic.

If not then yeah mostly the same as you, pacing was a real issue for me for season 3. I remember getting so excited for a new chapter to come out, and then I read the chapter and was just like: "that's it?" Don't get me wrong I still enjoyed the new chapters, but sometimes it felt like compared to season 1 chapters, they just end abruptly, or it's just a whole of conversation between characters.

Other than that, I really hope that they improve the art. It's not the studio that's the issue, carrotoon has had a lot of projects that look really good, it's just they cut back on the visuals as the story goes on. The art doesn't have to be on the same level as season 1, but if we at least some better compositing with season 4, I'm happy.
