This has led fans to suspect that her appearance on the show was foreshadowed all along.

On the drama front, Jung Eun-ji is set to star in KBS2’s upcoming series 24-Hour Health Club, premiering on April 30, while Seo In-guk is preparing for the release of Twelve on U+ Mobile TV and is currently filming Netflix’s Monthly Boyfriend with BLACKPINK's Jisoo.
