Nah you're not woke. It's just fiction and a kink like you said for some people who're attracted to the taboo. People take too many things at face value these days. Yeonwoo's explanation makes sense. He longs for her to be his sister cause it's one way to tie her down and he probably finds the play kinky, but they never grew up as real siblings so there is nothing that makes them that to be considered actual incest.
Thank you I thought I was going crazy
I dont see the problem with the sister fetish he is just a bit freaky no ? People with daddy kinks dont actually want to fuck their dad no ? or maybe im too woke
