1. Sangah

Since Sangah was a secret trainee who was never announced through CUBE TREE, not much is known about her. However, it is said that she passed numerous K-Pop auditions before joining Cube Entertainment—including Kakao M, MLD Entertainment, and CJ ENM.

The most well-known LIGHTSUM member, Chowon was one of the contestants on Mnet‘s Produce 48. While she originally ranked no.13 in the finale and narrowly missed the cut to join IZ*ONE, it was later revealed that Chowon was a victim of the company’s vote manipulation scandal. Her actual final ranking was no.6 overall.

Since the end of Produce 48, Chowon returned to Cube Entertainment and continued training. Last year, she made her movie debut in Bad Guy after originally training to be an actress. Some of Chowon’s skills and hobbies include playing piano, composing, and waacking, and she trained for four years and eight months in total.

Nayoung was also a contestant on Produce 48, but she was signed to Banana Culture Entertainment at the time. Sadly, she finished in 21st place, later signing with Cube Entertainment. However, she also passed auditions for FNC Entertainment, Woollim Entertainment, and Source Music.

Another secret trainee, Hina has very little information surrounding her. All fans know so far is that she attended MARU Dance Studio before debuting.

Juhyeon participated in two survival shows before joining LIGHTSUM: The Unit and Dancing High. Though she didn’t win either, she attracted a lot of attention for her incredible dance skills. She’s been dancing since she was in second grade, so it’s no surprise she’s so talented.

Jian was also a secret trainee, so she’s something of a mystery right now. One notable fact about her is that she’s one of the youngest idols in K-Pop right now, joining BustersMinji and TRI.BE‘s Mire who were also born in 2006.
