tripleS' Yooyeon has been cast as in a leading role for the new web drama 'Whats up.' 

'What's Up' is a web drama that shows the main character, Noh Mirae, struggling to find a job after many job interviews and ending up in a rut. Mirae's best friend, Lee Yujin, a broadcasting writer, is always by Mirae's side and helps her. 

Yooyeon plays Lee Yujin, a broadcasting writer. In a character introduction, Yooyeon said, "Yujin has many charms. I think the biggest charm is that she is a warm friend, but I think her tsundere appearance is really attractive. The words she blurts out sometimes are cute, and that's kind of Yujin's trade mark."

'Whats Up' is scheduled to premiere on April 7.
