Lee Yerim made her second debut in raw girl crush dance team girl group SIO.SIJAK in March with the digital single 'LA LA LA', after leaving Scarlet and graduating from Gyeongin Woman's University in practical music.

Yerim was born in 1992 and has been getting attention from companies since a very young age onwards. As just an elementary student, she received a casting offer from a big entertainment company (which one is unknown) for her unique dancing skills. Due to her parents opposing the idea of her being a trainee at such a young age, she declined the offer and stuck to dancing as a hobby. She started competing in several competitions and won some of them as well, gaining the nickname Gyeongi's Isadora Duncan. Isadora Duncan was a famous dancer from the 1900's who laid the foundation for modern dance.

In highschool, she started her own dance club and attracted the attention of her Scarlet's company FUNNY COLLECTION Entertainment. She debuted as Scarlet's leader and vocalist in February 2014, but left the group in March the same year due to an orthodentic surgery she had to get done.

And now she's officially back! SIO.SIJAK was supposed to debut last year in May with the digital single 'Tonight' but for unknown reasons the song was never released and after the two main vocals left, they had to re-group. Member Suna was promoted to main vocal from her earlier sub-vocal position and two new members, Sohee and Jiyoo, were added. Yerim offially holds the position of leader and rapper.
