Myung grew up on Eden alongside her best friends Isamu Alva Dyson and Guld Goa Bowman. Singing was a passion of hers, and her song "Voices" became popular during a school festival. The trio formed a love triangle that eventually erupted when Guld discovered Myung and Isamu sharing an intimate moment. This led to an assault by Guld, causing the group to break up and Myung to leave Eden shortly after. Years later, Myung returned to Eden as Sharon Apple's producer for her tour. However, it was revealed that Sharon Apple lacked emotions, and Myung's true job was to provide these feelings. When she reunited with Isamu and Guld on Eden, old rivalries resurfaced, and emotions long thought buried returned. Before resolving any issues between herself and her two suitors, Myung left Eden with Sharon Apple for Earth to commemorate the anniversary of the armistice between humans and Zentradi. Upon arrival, the awakened Sharon Apple imprisoned Myung in order to have unfettered access to Isamu and Guld. This also brought forth Myung's love for Guld but ultimately revealed her greater affection for Isamu. Despite this, Myung managed to free herself and put an end to Sharon Apple's manipulations. However, she took the opportunity to address any lingering emotions with her two friends.
