Kwanghee raised SECRET Sunhwa's suspicions after revealing his nail art skills on November 3rd's 'We Got Married 4'.

The ZE:A member brought his own manicure set to paint Sunhwa's nails. After seeing the expert way he handled them, Sunhwa commented, "Why are you so good at this? Have you done this many times before? How do you know [nail art terminology]?"

Kwanghee answered, "I haven't done it before," avoiding her. In the end, the on-screen couple had painted "Kwanghee's" and "Sunhwa's" on each other's nails.

Sunhwa was pleased with their efforts at nail art, proclaiming, "I'm going to show this when I'm on music programs."
