Weki Meki's Sei and Elly have been cast in the upcoming interactive web drama series, 'New Tale of Chun Hyang' (working title). 

A modern-day tale inspired by the traditional Korean folktale 'Tale of Chun Hyang', the web drama series tells the stories of young adults who are about to enter a new chapter in their lives. Previously, ASTRO's Rocky joined the cast as the story's male lead, Lee Mong Ryong. 

Now, Weki Meki's Sei has joined the cast as Sung Chun Hyang, a young woman working day and night to pay off her college loans. Fellow Weki Meki member Elly will play the role of Han Da Ni, and actor Kim Do Kyung will take on the role of Byun Hak Do.

'New Tale of Chun Hyang' is an interactive web drama series, meaning viewers can choose which ending to follow from a variety of options. The web drama is expected to premiere some time later this month.
