Shin Hyun Joon and Juni were spotted having fun off-camera.

On Friday, KBS Mon/Tues drama "Ohlala Couple" released behind the scenes photos of the 'Go sibling', Shin Hyun Joon and Juni. 

In the picture, the two of them were looking at the script together, laughing and even making secret faces behind the other's back. They seemed like real brother and sister and seemed very close.

In the drama, however, the two don't really get along. Juni and Shin Hyun Joon fight and argue over every little thing, especially over the issue of his ex-wife Yeo Ok (Kim Jung Eun). 

When the cameras turn off, the two actors are right back to being friendly and having fun with each other.
