Give Me Your Body, Grand Duke!

She possessed a character in a 19+ obscene novel called The Reason This Saint Has Become Corrupt It was a novel in which the female protagonist, one of the saints protecting the empire, seduces all the royal family members to share their holy powers and creates a reverse harem. She became one of the saints who died because she could not receive the holy powers. She possessed a body that couldn’t even make it to the end of the first arc. So in order to survive, she decided to target the Northern Grand Duke. He was the only one among the royal family members who had not been seduced by the female protagonist. She was worried whether she could actually receive the holy powers from him, but there was no other way since all the other royal families were taken by the female protagonist. So she went to the Grand Duke’s castle without thinking… Damn it, the rumors were accurate. The Northern Grand Duke didn’t feel anything no matter what she did. In the end, the only alternative she found was saliva contact, and she saved her life by slowly eating his powers through kisses. Then one day, she was protecting the Northern Grand Duke from a monster that came rushing into the castle, and her back got hurt. After that, the Northern Grand Duke became a bit strange. The guy who never kissed her first started kissing her without any reason, and he started to even be more initiative in physical contact. … No, what happened? “Why are you running away? I said I would give you a special chance.”
