The actor-singer couple decided to have an exercise session together, and Hong Jin Young had a particular plan before they even started. She said, "I'll be so sexy, you'll die." She continued, "When girls go to the gym, it's prettier when they tie their hair up loosely. Let's start stretching first,"�and took off her jacket.

Nam Goong Min as well as the guys in the studio seemed a bit surprise by her actions. He said, "I'm caught off-guard and don't know what to do because you suddenly took your jacket off. I don't know what I should do. I can't talk suddenly. Why do I feel embarrassed?"

The actor also taught Hong Jin Young how to do squats, which led to a discussion about both their bums. Not unlike the couple, they added in a 'Secret Garden' parody for viewers.
