you know... you guys forget that she's a reincarnated being right? she "was" or is* much older than him mentally speaking. Kind of a ditz or a sad adult to be controlled by a child.
It's funny how Cecil is supposed to be the genius but it looks like Bertia is more aware of her own feelings than he is
They balance each other out pretty well
@hanen
Its mentioned in chapter 1 that she "regained" her memories so thats not necessarily reincarnation.
She is still Bertia, but just with her previous life's memories.
I remember Cecil commenting on how similar Bertia is to her father, further signifying that Bertia is her own self and not her japanese self.
