Early life

Olivia attended Sung Shin (Sacred Hearts) Girls’ High School in Seoul along with Choerry. They are the same age. At first their classmates did not know she was a future member of LOONA because she was a trainee and could not reveal it until her teaser images were released, so she pretended not to know Choerry and kept her own identity a secret.
