The pictures show the two stars enjoying their outing as they shared cotton candy and drinks. Moon Chae Won smiled brightly as she pulled on Joo Won who looked like a little kid with his tiger headband.

The actors didn't lose their smiles despite filming for 5 hours in the scorching heat. Apparently, too many fans gathered at the scene after hearing that the two stars would be there, so filming was temporarily stopped and the shoot location was moved.

The producers commented, "Joo Won and Moon Chae Won's characters are growing feelings for each other as they care for one another with innocence and warmth. Their cute 'zoo date' will be 'healing' for the viewers too. Please look forward to their warm and touching love line."

Tune in to August 19th airing of 'Good Doctor' to check out their adorable zoo date!
