even the author of shuttline and wet sand spoke out about this
the way this is getting translated and uploaded every day I wish someone gave the same energy to my faves that have stopped uploading for months but already have several chapters in raws.
I personally don't find insest disgusting in bl. Personally, I prefer the dad/older brother/uncle(no older than that) to be the seme. Reverse psychology is hard to digest, if you know what I mean.
I don't know how to describe it, but I just can't see this guy being vulnerable, unlike Jiwon (bj alex). He doesn't show any other emotions throughout this story other than being aggressive. Right now, he doesn't even look like he has had any development..he's just angry that things aren't going his way.
deep down, this was secretly a doujinshi of plave.
