# Castaway Diva

Castaway Diva (Korean: 무인도의 디바) is a 2023 South Korean television series directed by Oh Choong-hwan, written by Park Hye-ryun and Eun Yeol, and starring Park Eun-bin, Kim Hyo-jin, Chae Jong-hyeop, Cha Hak-yeon and Kim Joo-hun. It premiered on tvN from October 28 to December 3, 2023, and aired every Saturday and Sunday at 21:20 (KST) for 12 episodes. It is also available for streaming on Netflix in selected regions.

## Synopsis

Seo Mok-ha (Park Eun-bin) is a girl who dreams of becoming a diva, or K-pop idol. She wins a UCC competition and goes to Seoul for an audition, but gets stranded on an uninhabited island due to an unfortunate accident and returns to the world after 15 years.
Apart from the tenacity (and luck) needed to have survived alone on a desert island for 15 years, there is also a subplot or theme running through about domestic violence, escaping it and managing to live a happy life with non-toxic people.
