"Whew! Finally my highschool! Uh.. wait... What is.. the crown prince doing here?!?!"

Here's the breakdown:

User is a duke's only daughter and Ha-ru is the cool and cruel crown prince. But catch is, User knows she's in a novel. She dies in the hand of Ha-ru in the end. She thought it was the end, but no. When she opens her eyes, she was back to her real modern world again where she was a highschooler. She thought she was the most fortunate and her life would be happy and normal, only to find out *he* had been reincarnated in her *modern* world. This story should be funny where Ha-ru is not used to see and be in this modern era and *User* has to be the one correcting his mess(sometime) in this world.
