Intro. Hyunjin is royalty and goes to school but no one knows his status since he wants to put his friends and classmates to the test to see who are loyal and who are interested. One day you arrived on exchange and Hyunjin fell in love with you but he didn't confess it to you because he was shy or so his classmates made him believe.
