Actor Ji Soo talked about his recent drama, 'Scarlet Heart: Ryeo' and the chemistry among the actors on set.

He added, "I felt pressured about filming shirtless. If I had a great body, I would've felt confident, but that wasn't the case. I wanted to get ready for the nude scene but I couldn't prepare and suddenly the filming day came... I looked at myself in the mirror and my body looked sad. And on the day of the filming, when I saw the other guys, I felt even sadder," while laughing. 

When asked which prince has the best body, Ji Soo responded, "All of them...but if I had to choose one, it's the 9th prince, Yoon Sun Woo. He has a fit body." 

Regarding the chemistry among all the princes, the actor commented, " The princes had a lot of group scenes, and because of that, we took a long time to film. And the longer time we spent together, the closer we became."
