Wonder Girls Alum Sunmi Teases Sister Bonding With Red Velvet’s Seulgi In ‘Secret Unnie’ Show

Former Wonder Girls member Sunmi has teased her upcoming appearance in JTBC4 reality show Secret Unnie along with Red Velvet idol Seulgi. Sunmi took to Twitter to tease their team up. She shared a photo and a couple of videos with Seulgi.

The photo features Sunmi and Seulgi lightly shaded lips while drinking some kind of cold beverage. Sumni wrote on the image "Love Mode." The first video, on the other hand, shows the two idols in their pajamas. Sunmi introduces Seulgi as "Bunny Seulgi" before turning the camera on herself and asking "Oh, who's this?" She wrote on the clip "coming soon" and "Secret Unnie" in reference to the reality show.

The second video features two TV sets. The message "Be sure to watch live" was written on the first TV monitor, while the other shows a photo of Sunmi and Suelgi. Sunmi wrote the hashtags "secretsister," "#secretunnie," and "#jtbc" in the caption.

Sunmi earlier appeared in a teaser for the show, where she expressed her excitement about having a "younger sister." She, however, did not reveal who she will be working with.

The Secret Unnie Show

It is a new reality TV show from JTBC4. It will feature pairs of female Korean stars who are not actually friends or haven't met each other. The dongsaeng hangs out with her older unnie for one day. Dongsaeng means younger sibling while unnie means sister in Korea.

The pair will be spending 24 hours together. They will share the same bed at night and their discussion about life, love, career challenges and more will also be featured in the show.

The two other idols on Secret Unnie are Red Velvet's Yeri and Boys Over Flower actress Han Chae Young. Secret Unnie airs every Friday at midnight KST on JTBC4.

Meanwhile, Seulgi and her Red Velvet bandmates are still promoting their first repackaged album, The Perfect Red Velvet, and its lead track "Bad Boy." Sunmi, on the other hand, made a comeback as solo artist earlier this year with a new single, titled "Heroine." It was earlier reported that Sunmi will also do a collaboration with BIGBANG member Seungri.

Sunmi first left Wonder Girls in 2010 to continue her studies. After a three-year hiatus from the music scene, Sunmi returned as a solo artist with her first digital single, "24 Hours." She also released her debut extended play, Full Moon, in 2014 and rejoined Wonder Girls the following year. The K-pop idol group disbanded in January 2017 after unsuccessful contract renewal negotiation with Sunmi and Yeeun.
