Nine Muses's Kyung Li appeared on MBC's 'Radio Star' on August 3 and revealed why she would greet others in 'American-style.' She explained that her hands would excessively sweat.
She went into detail with, "Because I sweat excessively, when I was learning guitar, the strings would become rusty, so I couldn't [continue learning]. Even when I was young, whenever I went to piano school, the dust and my sweat would mix to form dirty water."
She even showed how she would high-five using the back of her hand rather than the palm.
