On July 18 KST, MAMAMOO member/solo artist Hwa Sa appeared as a guest on the KBS cool FM radio program, 'Lee Eun Ji's Gayo Plaza'.

Introducing Hwa Sa to her listeners, DJ Lee Eun Ji remarked, "This week's theme is 'Please Take Care of My Tension'. Hwa Sa, do you have your own techniques for raising your tension?". To this, Hwa Sa answered, "I listen to upbeat music, or for my own secret method, I watch a concert clip from Beyoncé's 'Homecoming'. That clip is like my personal fuel." 

Next, Hwa Sa also mentioned plans for new music. She said, "I am working hard on my comeback. But the fans are crying, because I originally told them that it would be in mid-July, but with the Paris Olympics coming up, it will be pushed back until late August."
