Becoming the Wife of a Dark Cult Overlord

The sect keeps a woman it calls the saint, and its leadership passes down through one bloodline. Heejin is the one taken for the role. The man she has been seeing, Yohan, holds an ordinary office job as far as she knows, and inside the sect he is the heir it has been waiting on. "I will become a god if that is what it takes, just to have you," he tells her, and the orders he gives the men around him come without hesitation. The two of them plan a way out. Before it happens Heejin meets a man called Isaac, who tells her things about Yohan she had not heard, and after that she is unsure how much of him she can take on trust. They are both still inside the sect.
