Boyfriend composed of Kim Jong-seop and Park Hyun-jin chose Step by Step of New Kids on the Block whose members were extremely popular worldwide in the 80s and early 90s. I still remember three teenage girls were dead during the Korean performance at the moment.
Anyway, the two eleven-year old boys have never failed me this time. :)
