When mc sings a lullaby to the priest then suddenly fall asleep and forget what happen, it reminds me her cousin who said has a blood of a siren. when she sings no effect but mc sing has effect, it make me think, are the two swapped??? My theory wasn't confirm at that time when I read the story, now, it's finally confirmed (≧∀≦) my new theory rn is the cousin knows who her bio dad is and just playing the daughter role. And MC "father" the duke and her cousin are working some evil plot together that we don't know about.
AHHH WHAT I GUESS WAS RIGHT
MC was baby swapped
