Sung Kyu’s love for the band Nell made him famous – literally! On the show “Yoo Hee Yeol’s Sketchbook,” Sung Kyu revealed that he had gone to get an autograph from Nell and ended up auditioning, which led to his debut in INFINITE. (INFINITE and Nell were previously both under Woollim Entertainment.) Nell even took part in producing Sung Kyu’s second solo album, “27.”
