In a video that Luna just uploaded to her personal Instagram, Amber lures Luna into a small studio space and as soon as she walks in the door, her members begin screaming the happy birthday song at her while she freaks out.
It’s hard to tell which other members are in the studio, but Amber and Krystal were definitely present.
Check out the cute video showing Luna’s birthday birthday surprise on her Instagram and wish her a happy birthday!
