I hope in the end of the story Cain doesn't start doing some dumb shit to Jooin and then Jooin goes back to Yahwi. Not only would this make Cain's actions not line up (like calling him master and being nice), but it would make Yahwi's manipulation work and Jooin a 1 dimensional character. I know this author isn't the best with plots, but they could make it good or make it dull like their other stories.
