Cube Entertainment is back with the second episode of their 'Fantasy Land' teasers for their upcoming family concert! This time, the segment starts off with 4minute's Ji Hyun mass-texting everyone after she gets inspired by an idea on set. After drinking from a water bottle, she cheerfully chirps, "Do you know, do you know?", and informs everyone of a special water event at the concert. She adds that it'll be refreshing, and that everyone should prepare to get wet. Watch the hilarious reactions from the Cube family as they ponder over this new development! The "United Cube Concert" will take place on August 14th. Fans can grab tickets through the Interpark website starting from June 14th at 8:00PM KST!
