From Tappytoon:
Adelia suddenly finds herself transmigrated into an RPG game. Knowing that her character will go off to become the villainous witch that meets an awful demise, she decides to choose all the dialogue options that will prove she is the furthest thing from evil. But this gets her tied up with the brutal male protagonist, Siegfried Scarborough, who is supposed to be the one to eventually kill her. When one wrong choice immediately leads to death, will Adelia find the right playthrough to get her the good ending?
