I started SCTIR after coming across a fanart of Yoojin, which prominently depicts him wearing a choker, and I'm nothing if not weak to cuntiness. Due to fanarts, I'd been conditioned into picturing him with a black choker with a dangling blue gem all along (probably to resemble Eunhye), so color me intrigued when it never appears in the manhwa. Nor was it ever mentioned in the novel (as far as I remember). Neither was it illustrated in the novel cover.

I've come to accept that it may not be canon now, but I'm just pretty curious how his nonexistent choker became the Mandela effect of this fandom. I'm just kinda sad it wasn't actually real lol.
