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.^[8]

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.
