Everyone knows how much Dara loves her little brother Thunder, and fans will get to see her older sister love in action on the upcoming 'Secretly Greatly'!

Thunder will be pulling off a hidden camera prank on his older sister. Thunder reveals to Dara that he's gotten scammed by his partner in a business involving cats. Just like a normal older sister, Dara is at first angry at her younger brother for doing something idiotic, but her concern quickly overcomes her anger and she reads carefully over the contract to see if anything could hurt Thunder.

She actually stood in front of Thunder to physically protect him when others that were scammed came and started making a fuss. The episode will air on the 8th at 6:45 PM KST!
