Urban Dictionary defines Queerbaiting succinctly as: “When an author/director/etc. gives hints, and clever twists to paint a character as possibly being queer, to satisfy queer audiences, but never outright says they are so they can keep their heterosexual audience.”
This manhwa is pure straight romance. Yes, it is no doubt that COUNTLESS of people saw the cover and thought it was BL but that isn't what queer baiting is as you can see with the definition i pasted above. There is also nothing about this that seems "baiting" as we are humans who can read the existence of tags specifically made to tell the reader's what the story is about.
yeah this is just straight queerbait, I did read tags, no this is legitimately queerbait
