It's not
Then who is it?
SPOILERS
The hooded person is supposedly the author of the novel and they're possessing the body of their character - Lize (so it kinda is her?)
It's probably that bald girl we saw for a minute, in a previous chapter
What bald girl?! Are you even reading the same manhwa? Do you mean the girl in the hoodie?
They meant the girl in the hospital from one of the fl memory
This is just my theory but the hooded person is not Lize , the blonde girl, that would be too cliche and predictable. Their ID is still a mystery otherwise the author would have showed it. It’s actually the Princess, purple short hair. She’s obsessed with Lize and hates Edith for no reason. ITS DEFINITELY THE PRINCESS.
