She is quite literally the embodiment of a Joonghyuk in one of their many regression turns. Somewhere in her turns, she eventually become the goddess of death by inheriting it. Perhaps she did it for her twin so she could sacrifice herself.
Sometimes I wonder if 216 meant that it is her tritype number. She is no doubt a triple compliant tritype number if that really is what her character is about. Perhaps she has ascended to the suffering of an enneagram core 4 by being first a core 2 and sacrificing herself.
She does it all for the sake of her sister which is the greatest sacrifice of love, curse, and death. I love how she exists as she has written as that really is the ORV—Bible spin off in how she would of loved to written herself.
Maybe somewhere in the universe, she has written herself as someone who is mysteriously dead or not alive. My personal incarnation who I love the most reminds me of this woman. Yet my personal love has chosen to be the pink hair woman who chose to sacrifice her entire existance.
She used to be someone on the destruction path then it was a different path in one of her past lives. It is very interesting and fitting.
