Can someone explain please why she said "do understand why I told you Seth's weakness?" I thought she wasn't going to tell him. Is this a mistranslation?

Yes they are, in the sense that they are the connected with the seeds of doubt Osiris planted in him, making him believe that the real reason Neftys didn't consult with him about their difficulty to conceive and went to Osiris instead was (according to Osiris) because Neftys had known dep down that Seth was weak and powerless compared to Osiris.
Wow the comment section is so weird. I know we're here to read mangas illegally, but you do realize that posting here is affecting somebody's mental health in a SERIOUS matter. It's just a manhwa, you won't die if you don't read it for free. If it's so important to you, then you can get out of your comfort zone and go donwload lezhin. Again, Im here on mangago myself so of course i read stuff illegally too, but we should all understand that the situation is important and we should have some empathy towords the author. It's the right thing to do
