Why is the idea of Areum being the daughter of evil and Jeaki being the servant of evil so appealing to me? Like I've been dabbling with it for a while now and it's just like... I like it so much? Like, in that time, I could imagine Jumin being a king and marrying his servant, Jaehee, turning her into a queen.

They have Jeaki and Areum. Areum, dispite being younger, is the the queen when something happened to both Jumin and Jaehee. I can imagine Areum becoming like the daughter of evil if she had too much power in her hands.

That's probably why I unconsciously made the decision to let Jeaki inherite C&R. Anyways, I think that Areum would be Rin, Jeaki would be Len, Gyeong would be Kaito and Jisu would be Miku.
