'Produce 101's Park So Yeon and Lee Soo Min will be debuting together.
Park So Yeon and Lee Soo Min were both 'Produce 101' season 1 trainees, and Lee Soo Min came out on yet another audition show and placed third in 'K-Pop Star'. She had originally been from Fantagio but left, and ultimately joined Loen Entertainment after 'K-Pop Star'. Recently, Loen Entertainment opened a Twitter account called Loen Girls featuring Lee Soo Min and Park So Yeon and a third trainee who has yet to be fully named (she is introduced as Ranyoung in the letter she and Park So Yeon wrote to Lee Soo Min).
Loen Entertainment revealed, "The girls don't have a set debut date yet, but we are training them while aiming at a debut next year. The girls' progress, along with the other girls that are training with them [for the same group], will be uploaded continuously on 'LOEN GIRLS'."
