GLG's rookie girl group H1-KEY would like to formally introduce you to its brand new member, Hwiseo!

Previously, ahead of the group's first ever comeback since debut, GLG announced that H1-KEY would be adding a new member to its lineup, after member Sitala's departure from the team earlier this year. The new member joining H1-KEY beginning with the group's July comeback is Hwiseo, leaving a strong impression with her electric blue and blonde hair!

H1-KEY's first comeback since debut with their 1st Maxi single album 'Run' is slated for July 5 at 6 PM KST. The group will be kicking off teasers later this week.
