Joshua Hong (Hong Ji-soo [홍지수]; born December 30, 1995), known mononymously as Joshua (조슈아), is a Korean-American singer-songwriter under Pledis Entertainment. He is a member of the boy group SEVENTEEN and its Vocal Team sub-unit.
As the show's popular theme song explains, fictional Will's mom sends him away from his rough Philadelphia neighborhood to live with wealthy Uncle Phil and Aunt Vivian in Bel-Air. Will often has fun at the expense of stuck-up cousins Carlton and Hilary.
