Mini albums


  • LOONA 1/3 initially derived its name from it consisting 1/3 of LOONA's members.[citation needed]
  • A second meaning to the group's name occurs when their numbers are flipped to create "3 / 1". The "3" is said to represent HeeJin, HyunJin, and HaSeul (the first three members to be introduced), the "/" is YeoJin (YeoJin was revealed after HaSeul, making her a break between the reveal of members of LOONA 1/3), and the "1" represents ViVi (she was the sole member to be introduced after the break).[1]
  • LOONA 1/3 is currently the sub-unit with the most MVs.
