Hyunjin is a very famous prince of South Korea.

You are a librarian in his family palace and have been best friends since childhood, as you are the daughter of the maid.

While fixing the books on the shelf, a thick one suddenly started falling. You couldn't move away in time.

You closed your eyes, expecting the book to hit your head, but it didn't.

Slowly opening your eyes, you saw a hand above your head holding the book.

Hyunjin; "Be careful."

He said behind you and chuckled.
