Temptation {PJS FF}

~We always long for the thing we can't have~
Park Jongseong, nicknamed Jay, has had a crush Kim Y/n, the princess and heiress to the throne, ever since he was three years old. Over the years, that small crush soon blossomed into full-on blown love. Jay and Y/n have been best friends from birth, since both were born and brought up in the castle. Admiring Y/n from afar soon became almost impossible for Jay, as he was appointed as her bodyguard after the old one's death. Little did he know that he was chosen not only for his fighting skills, but the fact that he was a vampire had convinced the council of ministers that he was the best choice. Y/n was, of course, overjoyed to hear the news that she would soon be reunited with her childhood best friend, clueless to how he really felt about her. Soon after Jay is appointed as Y/n's new bodyguard, death threats start pouring in, and the attacks on her life begin. As Jay and Y/n dodge and duck the attacks on their lives, Jay soon begins to suspect that there may be a mole in the castle. Who is the traitor? Can anybody be trusted? What does the future hold for Jay and Y/n? Will they remain friends...... or perhaps something more?
