Group ZE:A's member Park Hyungshik went crazy as Girl's Day's Hyeri danced.

In KBS2 "Immortal Song" aired today, the 70s music special was held.

On this day, Park Hyungshik said, "When Girl's Day is talking, I'm all ears. I'm focusing on every word they speak," not being able to take off his eyes from them.

ZE:A members said, "Hyungshik watches girl group stages when he comes home from 'The Real Man'" and Park Hyungshik danced to Girl's Day's song "Expect."

At this, Hyeri started dancing as well, approaching Park Hyungshik slowly, and Park Hyungshik watched nervously, not knowing what to do.
