This is INFINITE's first cheering guide video. INFINITE is a 2.5th generation idol, and since they made a comeback 5 years ago, this is the first time that all idols do these days. When Sung Kyu made his solo comeback, he was asked by fans, but he refused, saying he was ashamed of himself. But he promised to make a cheering guide video when he made a comeback with members, and he finally kept that promise.
