tvN's highly-anticipated new Sat-Sun drama, 'Castaway Diva', has revealed a romantic new teaser poster featuring Park Eun Bin, Chae Jong Hyup, and Cha Hak Yeon.

'Castaway Diva' tells the story of a young woman named Seo Mok Ha (Park Eun Bin), a miracle child who survived all on her own on a deserted island for 15-years before being rescued. Ever since she was young, Seo Mok Ha has dreamt of becoming a singer. 

After returning to civilization, Seo Mok Ha sets out in search for a mysterious person named 'Ki Ho', who helped her realize her precious dream during her youth. Moved by Seo Mok Ha's story, a broadcasting station PD named Kang Bo Geol (Chae Jong Hyup) and a news station reporter Kang Woo Hak (Cha Hak Yeon) decide to help the heroine on her search. The two brothers are expected to deliver a sweet chemistry with Seo Mok Ha. 

'Castaway Diva' starring Park Eun Bin, Chae Jong Hyup, Cha Hak Yeon, Kim Hyo Jin, and more is set to premiere later this month on October 28 at 9:20 PM KST.
