After his soul crosses into another world, Luo Wei goes from "he" to "she."
Along with a cheat ability, the [Witch Contract System], she gets saddled with a bizarre [You'll Die If You Don't Cuddle Witches] debuff:
She has to draw "witch power" through intimate physical contact with witches in order to stay alive.
So Luo Wei uses the System to impersonate a goddess, luring witches hunted across the continent to seek her protection, securing a steady supply of "witch power."
The plan works: one distressed witch after another throws herself into her arms, but they seem a little too enthusiastic:
"Goddess, you're the best goddess ever! Please hug me!"
"Goddess, let me carry out your will!"
"Goddess, you wouldn't want our little secret getting out to the other witches, would you?"
[The protagonist's approach: If she can handle them, she takes the lead. If she can't beat them, she submits for now, then turns the tables as soon as she gets stronger or finds leverage.]
