Sometimes I forgot that the Manhwa doesn't went adapt completely in a different way from WN.
About Master's seductive body the Manhwa doesn't show much and only mentioned some part as having body that is seductive or the mark that only owned by Queen Succubus.
In WN, the Master's body legit make anyone who saw her went insane on first sight and tries to have their way with the Master right away although the whole thing revolve mostly on femalexfemale action but still very close to rape regardless which is why they completely took a different direction in the comic.
