I'm pretty sure, there have been some hints from the previous chapters :)
im kinda still sus about this. coz wouldn't the demon kid–the one so bent on finding lilith, know if she's the daughter of lilith? They're basically twins. And he already saw catherine on that boat.
Tbh, lilith's crafty as fck so I wouldnt be surprised if she did something to hide her connection to MC. Ntm that his connection to lilith may not be applicable to MC.
Oohhh possible. Maybe she's trying to protect catherine from something bigger, and that's why she's in hiding too (I really hope that she's alive)
He didn't see her on the boat tho. He was summoned, immediately had that chat in the abyss where she hid the whole time, while that happened her physical body was taken to her room.
The way things are going, The kid demon seeing her and realizing who she is or thinking she is Lilith or something Is likely gonna be a future plot point. either he will try and take her away from the Duke or he will want to kill her in a "you are the reason she's gone" kinda way. Or they team up to find her mom. Wouldn't surprise me if the Duke knew the entire time either from this past meeting or cause he knows what Lilith looks like and that ends up being the relationship conflict that always happens to ruin the honeymoon period after they become official.
all these are conjecture tho lol I am excited to see how it actually turns out.
Her mother's Lilith, isnt she?
