IU looked like she was having a blast during her outdoor trip with co-stars Lee Ji Hoon and Choi Kang Won for 'You're the Best Lee Soon Shin'.

The behind-the-scenes photos show Young Hoon (Lee Ji Hoon) taking the restaurant staff on an MT. When the cameras weren't rolling, IU, Lee Ji Hoon, and Choi Kang Won were seen enjoying an MT of their own by sharing refreshments and laughs. 

As IU and Lee Ji Hoon's characters have been getting closer in recent episodes, viewers have been left wondering what will happen on this trip and Soon Shin's (IU) relationship with Jun Ho (Jo Jung Suk). 

Tune in to find out on 'You're the Best Lee Soon Shin' this weekend!
