K-pop artist SUNMI and girl group Red Velvet's member SEULGI showed their sisterhood.

On April 26, SUNMI shared a series of photos and videos taken with SEULGI on her social media account.
In her first post, SUNMI and SEULGI are wearing cute pajamas and SUNMI introduces SEULGI as "Rabbit Seulgi."

In another post, SUNMI and SEULGI are enjoying some beverages together with the message, 'Be sure to watch it live.'
She also wrote 'Secret Unnie' in her post, which appears to be a reference to the new reality show with the same name ('Secret Sister').
JTBC4's new reality show 'Secret Sister' features pairs of female celebrities who aren't close to each other yet.

They spend a whole day together, including talking about their lives and sharing the same bed at night.

Previously, another Red Velvet member YERI paired up with actress Han Chae Young.
