Infinite’s leader Sung Kyu attempted to reach the title of ‘Ultimate Cool Guy’ on Mnet’s Infinite Rank King, where the members decided to hold a modeling competition.

From beginning to end, Sung Kyu continued to insist that he was a cool guy, even telling his stylist that he’s so cool that he doesn’t cling onto a girlfriend who wants to leave.

But his coolness was tested when he came across Woo Hyun, who began criticizing Sung Kyu’s outfit.

Woo Hyun, ranked five, approved of the white pants that Sung Kyu, ranked six, brought, but when Woo Hyun saw the blue jean shirt, he said, “This is the color of the ocean! Can you swim?”

When Sung Kyu replied negative, Woo Hyun immediately failed the shirt, declaring, "I would like him to wear something else."

Sung Kyu remained cool - but wasn′t sure if Woo Hyun was trying to con him into losing...watch and judge if Woo Hyun was a help or a hindrance!
