In the episode 6 of SBS’ Rooftop Prince broadcast on April 5th, 2012, the scene of Park Ha (Han Ji Min) arranges the ranking for the foursome Joseon Dynasty handsome men in the coffee shop is provoking laughter.

Park Ha tells Do Chi San (Choi Woo Shik) not to call Lee Gak as Your Majesty, as in modern society, most people calls brother (oppa) or senior. If the person is same-age peer, then can call name directly. Then the Joseon Dynasty foursome gang announces their age individually.

After learned of the age of everybody, Park Ha said, “Then I’m your sister now!” At this time, the crown prince’s expression instantly turns stiff.

Audience said, “Now crown prince is no longer crown prince, looks at the stiff expression of Park Yoochun,” “Now began the life as modern person” and so on.
