Sunmi is no exception when it comes to Seulgi's fatal charm.
In a recent episode of 'Secret Unnie,' Sunmi and Seulgi dressed down comfortably in their pajamas as they reviewed their music videos together.
After Red Velvet's debut music video, 'Happiness,' the group's latest release, 'Bad Boy' came on. Sunmi who personally loves the song was watching over it lovingly. The both danced a little to the choreography before the part where Seulgi circles her hips came on in the chorus and Sunmi immediately gave it a spontaneous cheer.
Sunmi mentioned how she thinks that "This is a song for Seulgi" making the Red Velvet member all shy.
