There are so many little details and foreshadowing in the story. Even the details like the walls having Nephthys conversing with Osiris in way earlier chapters that you wouldn't notice unless you reread it. I hate male characters being threatened to have a womb and a child but it works here because they are all gods and have magic, and even then the magic is still following a strict internal rule set even if its more of a symbolic rule than concrete stuff. I like that no character is exactly how they appear, and yet what is reveal of them makes perfect sense. Its a rare manhwa that put a lot of effort in its story. Rather than just porn or cheap drama.
