Materialistic Princess

Read manhwa Materialistic Princess / 물질만능주의 공녀님
One day, I woke up from being a poor college student as Princess Roselia Kanep from the novel ‘A Sculpture of Emotion’.
And by the way, she was the daughter of a poor noble family who’d squandered their wealth under her brother’s leadership. In order to earn a fortune, she uses the original content of the novel to approach Anoch, the crown prince who lost part of his soul under the curse of a witch.
“Your Highness, I’m an expert in emotions,” she said. And so, he started wondering if she could help him.
“Come on, put feeling into it! Emotions!” Roselia kissed Anoch’s lips.
A side character somehow deviates from the original plot?!
