not sure if you've read the recent chapters but
there wasnt exactly an actual big shocking moment. but i think what you're tryong to find is atound chapters 80-100 I cant remember the exact . but it's around there.
and the scene was more like everyone kinda knew (the mc's brother, the father, the pope, and even later on the MC) and they're just waiting for something to happen. or just waiting for MC to realize it or shit.
granted at the start mc didnt notice and the others were kinda vague about it. but later on MC was already putting the pieces together and she didnt want to believe or speculate and just waited for ML to tell her but it didnt exactly happen that way. and she had to learn about it thru Chloe and thru ML meeting up with his brother aka the prince and shr wasnt exactly a surprise surpise moment
Can anyone tell me when people find out that Killian is actually a prince!?
