Later when the idiot climbed into bed, everyone thought she would not survive the night, but they never thought that she would become the cinnabar mole of that lunatic. Prince, she is a subjugated princess who pretends to be a pig and eats a tiger. She is not from the right family, but she is actually a book lover.
