Ahhh forget I said this lmao, don't @ me but I just find the art style weird "sometimes" like the size of the head,face and body proportion is weird. But looking at this again it's probably just on weird occasions so I don't blame the artist. Also please forgive me for saying "lazy" to the author haha I dont mean it to belittle the author (●'◡'●)ノ
It's not just you I noticed it too. As the chapters progressed the art slowly went downhill. Not saying that the current art is bad, but the change is noticeable compared to the earlier chapters. If I were to see Ch1 Jaehyun vs Current Jaehyun without knowing it's from the same artist, I'd honestly think they were done by different hands. Either way I don't mind the art that much in this story, I started reading for the plot anyways ლ(´ڡ`ლ)

I know making this probably takes time and effort but I just can't get over the feeling that the style is getting lazier compared to the first few chapters, and what's worse it their face changes so often it makes it look like it's another story after another. ugh hope it's not always like this and the author probably take time to actually make the art better like the first few chapters. Fighting!
