Scarlet Heart: Ryeo casts join Running Man in search for Rebellion of Princes.

Episode 314 of Running Man features the 3 main leads of the new SBS drama Scarlet Heart: Ryeo with seasonal actors Lee Jun Ki, Kang Ha Neul and Hong Jong Hyun. The opening of the episode cracks everyone up with Jong Kook, Jae Suk and Kwang Soo dressed in women's hanboks and head dress. They looked hideous and terrible too. Ha Neul and Jong Hyun kept laughing away seeing how awful they look. 

There were 3 teams of Princes and enters in Emperor Jun Ki who was all charismatic in his royal dragon garb followed by Eunuch Suk Jin! The fellow Empress and Consorts were dissing out their unsatisfactory in the household while Emperor Jun Ki tells them he is choosing an heir to the throne. He throws a scroll of command by a certain date where the moon and sun meets, a Crown Prince must be selected for the throne. 

Fast forward to the future, the 3 handsome Princes were seated in a cafe receiving a scroll. Since Jun Ki is particularly new to RM program, he is given a special chance card. Jong Hyun sprints out the door upon reading a mission which is to interact with the public. Poor Ha Neul couldn't find anyone who knows who he is! Confidently Jun Ki finds two female fans in the public who were going ga-ga over him and each of them has to ask the citizen what is their name and they must play a mission- Two Bodies, One Heart. Example- Cola and Cider- both must give the same answer otherwise choose another citizen. Upon getting the same answer, the Princes must hurry to the gate by playing a ball game where they duck and receive two balls into their head crown. 

While everyone was busy dodging the head balls, Jun Ki was having his own fan meeting snapping photos with public! Hahah!
First to get through is Jong Kook followed by Haha and the rest and last two were Ji Hyo and Jun Ki. 

Now the 10 Princes were given a mission to use an air hammer to eliminate the others by hitting them on the back of their head. The back of their head has two hearts. If they lost the two hearts, they are out. The last two that came through the gate must find their own air hammer balloon. Ji Hyo immediately found her hammer and started hounding on her preys. Jun Ki finds his hammer hidden too and started immersing himself in the role. He takes on Jong Kook while Ha Neul easily took off Ji Hyo's heart. Jong Hyun was pretty swift as well.
The 4 winners- Kwang Soo, Gary, Jun Ki and Jong Hyun proceeded to a nice swimming pool where they were to shoot arrows at the teddy bears containing names.
Gary and Kwang Soo starts whinging that Jun Ki and Jong Hyun will win the race because they have just filmed the sageuk drama. Jong Hyun denies flatly shaking his head he has never shot any arrow before... Hah! His teaser and promotion shows he is holding a bow and arrow in the drama! 

It has proven Jong Hyun is a skilled archer! He managed to eliminate the rest easily and scored a chance card. Jae Suk laughed seeing how Jun Ki tried hard but also keeping his image and pose. Instead he shot down his own teddy bear name! Disaster!

Meanwhile the earlier 6 losers of the hammer mission were to fight and defend themselves on the pool filled with mud water...eeewww....
As expected big nose brother Suk Jin was oust immediately by Haha. So he cannot play for the final mission game- ripping name tags. Instead he became an announcer for the rip tag game.

The 9 Princes adjourned to the working building where they are to run around and find the golden cushion. They have to sit on the cushion for 3 minutes and to fend for themselves to ensure the person they wanted to eliminate gets oust. Ha Neul tried to rip Gary's name tag but he failed. He wasn't quick enough so Gary ripped his telling him he hasn't mastered the skill yet. But to Gary's shock, Jong Kook crept behind him and easily tore his tag! Muahah!

Gary didn't survive long after eliminating Ha Neul as he felt the most embarrassing moment of his life. Kwang Soo betrayed Haha and as Jun Ki tries to help them out however Jae Suk sneakily rips off Jun Ki's tag from behind. Awww poor Jun Ki! He wanted to survive longer as he promised his niece he will win the race. 

Jong Hyun, Ji Hyo, Jae Suk and Jong Kook were the remaining ones at the very last minute. As they tried to fight off Jong Kook, he was strong enough to rip off Jae Suk's name declaring himself a winner- the heir to the throne. Ta-dah! 

Eunuch Suk Jin presented the royal robe and crown for Jong Kook's coronation to which Jun Ki pointed out that's his garb for his role in the drama! He wasn't happy...poor fella.
He promised he will be back for the next mission to win. The rest pushed Jong Kook back into the stage and closed the curtains since they are getting used and bored with his usual winnings.
