Park Myung Soo got shy in front of Lee Na Young.

On 4th, the new episode of MBC 'Infinite Challgne' showed Lee Jun, Lee Tae Sung, Defcon, Lee Na Young, and Infinite Challenge members leaving for a camp.

Before leaving for the camp, other members except for Park Myung Soo and Lee Na Young went on grocery shopping, and the two were left together on a bench.

As Yoo Jae Seok saw the two sitting together, he said, "Park Myung Soo and Lee Na Young together. This is a historical event. Who would've even thought about this?"

Park Myung Soo also said, "I didn't even imagine this as well."

However, Park Myung Soo started getting very shy in front of Lee Na Young as the time passed, and kept making awkward laughters.

Park Myung Soo tried hard to get rid of the awkwardness, playing various games, and turning music on, but it didn't go away.

Jeong Jun Ha said, "Lee Na Young knows how to respect elders," and Gil said, "Lee Na Young has been seeing handsome guys only, and she's just interested in something new."
