To become a witch, one must have sex with someone. However, we knew that the partner of the sex would not be there after the sex since we saw no witches that have a partner before. Thus, we knew that if they do the deed and perform the ritual, the MC could legitimately die or worse, his body become a vessel for whatever demon that she makes a contract with to become a witch. That's why she said she don't want to involve him with her world and she would find a way for her to become a witch without the sex ritual. Because she genuinely love him, and the thought of using his body and losing him forever is not something that she wants.yeah i have no idea what happened so can a kind reader break down the chapter for me
The frog thing is probably because she doesn't want to see him for a while, it happened. And meeting him in the dream is a way for her to see if he is serious with his love to her or not, or is he just wanna bang.
