Castaway Diva

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, gets stranded on an uninhabited island due to an unfortunate accident and returns to the world after 15 years. Trying to readjust to society, she gets the chance of a lifetime when her idol is performing at a local event, although she is washed up due to being washed up during those 15 years. Wanting to give back to her idol's being her reason to live, she becomes her idol's manager, helping her achieve stardom once more. 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.
