Actors Park Joo Hyung and Ok Tacyeon posted a proof shot while filming "Wonderful Days".

Park Joo Hyung and Ok Taecyeon show off their brotherhood and friendship on KBS drama "Wonderful Days." They posted a photo they took while filming on set wearing raincoats on a rainy day. They were spotted wearing black coats and hoods.

The photo was posted via JYP's Facebook, and both of these actors are wearing their hoods instead of using an umbrella. They're both looking at the camera with eyes full of charisma, and sporting innocent smiles or playful tongue protruding, which are eye-catching.

The two actors are actually in the same agency, and word has it that they support and encourage one another on set.

"Wonderful Days" airs every Saturday and Sunday evening at 7:55PM.
