Number Six(2018)

Number Six is a South Korean drama that reunites six lifelong friends a decade after they parted ways for college. Won Tak, Min Joo, Eun Kyung, Chang Kyung, Se Joon, and Se Ra once shared everything—or so they believed. When they reconnect, long-buried secrets surface, unraveling a complex web of hidden romances, unresolved feelings, and the painful truth that even the closest bonds can conceal profound betrayals. As the group confronts what they've kept from each other over the years, they discover that the bonds forged in childhood are far more fragile and complicated than nostalgia suggested. The series explores how time, distance, and life choices reshape friendship and reveal the people we thought we knew best.
