Gary dedicated a song to his 'Monday girlfriend' Song Ji Hyo on the latest episode of 'Running Man'!

At the end of the day, the teams separated into tents for the night. With ZE:A's Dongjun and Gary in one tent, they played some music to help them drift off into sleep.

Drawn by the sound, Song Ji Hyo paid them a visit, asking about the song. "It's a theme for you," he told her.

Although in reality, the song that was playing was called '5 on a Joyride' by Cody ChestnuTT, we're sure she appreciated the gesture!
