Noh Yoon-seo shouted "Yay!" at the news of Nam Joo-hyuk's casting.

I was watching a talk video of Noh Yoon-seo and Nam Joo-hyuk promoting *The Crown Prince*, and their chemistry was delightful.

It was cute how Noh Yoon-seo didn't hide her honest feelings, saying she shouted "Yay!" when she heard the news that Nam Joo-hyuk was cast.

I heard that they became really close while filming, relying on each other and joking around, so maybe that's why I found *Donggung* fun.
