During the filming, upon entering the organic-strawberry field, the curious Suh Joon opened his eyes widely and ate a strawberry that wasn't ripe yet. Despite the strawberry not being ripe, he couldn't hide his delight and amazement at the taste. Suh Un also showed his love for strawberries by grabbing one with each hand. Seeing the way they devoured the fruit, their father Lee Hwi Jae laughed at their adorable fascination and appetite as he wondered out loud, "Who are you guys?"

Stay tuned for their eating broadcast ('mukbang') this Sunday at 4:50 PM KST!
