Just as announced, TripleS is preparing to release their first 24-member album and introduced the final four members - Kim Chae Won, Sullin, Jeong Hae Rin, and Ji Suh Yeon.
In the teaser videos released in the past few days, each new member was given a chance to flaunt their unique individual charms in various settings.
While Kim Chae Won showed off her rebellious side, Sullin set off on a free-spirited trip, Jeong Hae Rin displayed her playful charms, and Ji Suh Yeon showcased her grace as a ballerina.
Previously, there were 20 active members of tripleS and with the addition of four more members, the group has begun preparation to promote as a 24-member group.
With the 24-member album release in May, tripleS will become the largest K-pop girl group in terms of number of members. Until more members are added, the group will remain the second largest K-pop group after NCT (26 members).
BTW Suhyeon's name is actually Seoyeon, same as the first member. They spelled it differently so we can tell them apart, but it's misleading. There will be a special Gravity to decide stage names for Haerin and Suhyeon.
