New vocal trio Lush is making its first step onto the music scene with debut single “Feeling Insignificant” and is planning to be recognized with members’ impressive vocal talents.

Lush is apart of Oscar Ent, home to artists such as Bobby Kim and Double K. The members are Kim Ji Hae, Kim Min Hee, and Yoo Sa Ra, who are all 25-years-old and were a part of Korea’s best army chorus group.

The group’s title song “Second Crush” is a medium-tempo track which expresses about the couple reaching the end of their relationship.
