this is my opinion but i guess the case somehow related to the ideun’s family company i mean they all seems sus even the chief prosecutor?? the old man. and bc ideun want to bring down his family thats why he let himself live like that you know like how everyone said that he sleeps with diff people. damn idk but i can’t trust the police lol this is so interesting
is ryujin becomes a demon now bc imae keep saying lust demon???? lol
No. Remember that ryujin's body attract demon. So, I think he used his body as a mean to trap demon in him. And sometimes lust demon possess him or something.
