Seichciteen Members Oldest To Youngest. The older member is s.coups, whose real name is choi. Though seichciteen has 13 members, their name comes from the equation, “13 members + 3 units + 1 team = seichciteen.” their fans, known as carats, shower.

So i’m posting this blog bc i was in this seichciteen group chat and people are having some confusion with the age order. The older member is s.coups, whose real name is choi.
