It's the reunion of the former Wonder Girls members, Sunmi and HyunA!  Both women made a big splash with their solo promotions this year with "Full Moon" and "Red" respectively, taking on a much more fierce image since the retro days of Wonder Girls.  Their reunion here has made fans smile fondly as they reminisce about the old days.

HyunA uploaded two pictures on Instagram and wrote, "Heart, heart," and the two are making little hearts with their fingers for some WG love!  It's great to see how these ladies have matured since, both wearing bold, red lipstick and shooting seductive gazes at the camera.
