The family soon rushes to the hospital while Bong-wan writes his suicide note, addressed to his wife and sons.

On the other hand, Mok-ha begins a part-time job to support the now Lee family, unaware that the brothers have gotten their jobs back. Meanwhile, the Lee couple have also gotten new licences with their original identities and have reopened the salon. Woo-hak, now named Lee Chae-ho, has also changed his attitude and has become more expressive towards his family so as not to leave any regrets behind.
Meanwhile, Ran-joo refers to a lawyer to see if she could win a case against Seo-jun with the invoice but doesn’t take upon the same. However, when Seo-jun exchanges tracks between Mok-ha and Mo-rae, she rushes to question him and brings up the invoice as well. Seo-jun tells her that her mother had shredded the document and had always wished for her to be a singer and not a president.
Ran-joo is shocked by this revelation and the two make a bet; if Mok-ha tops the charts with his changed track then Seo-jun will keep his position and shares, if not then she will leave it all for Ran-joo. Elsewhere, Mok-ha and Mo-rae end up listening to each others’ songs and cannot help but appreciate them.
Upon Ran-joo’s return, Mok-ha excitedly requests to go along with the exchange and is ready to record Mo-rae’s track. She later tells Chae-ho about the same and he opposes giving her track to Mo-rae, he goes along with Mok-ha’s decision. Mok-ha then tries to give him money for their daily expenses which is returned by Chae-ho as he tells her that they have gotten their jobs back.
She then tells him to pass the money to Ki-ho as he had paid for the apartment that she is now staying in. Chae-ho is shocked by this revelation and when he confronts Ki-ho about the same, Ki-ho tells him that finding Mok-ha on that island was not a coincidence, but fate. He had spent all his time and energy looking for her and he finally did find her.

Castaway Diva Episode 12 Review
Castaway Diva finale closes the story of Mok-ha with a happy note that leaves us with a happy feeling, making us hum to a tone with a smile. The show gave us an ending that we all know we needed after what happened yesterday and while some may say that Bong-wan deserves better, well I would not agree as his intentions for this were never right.
Meanwhile, Ran-joo has found a new journey in her life, going from a singer to a producer is perfect for her as she is a true musician in every way. But seeing what she does for Mok-ha’s first stage brings some very heartwarming feelings that show how wonderfully a woman can support another woman.
Similarly, the appreciation Mo-rae and Mok-ha hold for each other when listening to each others’ music also shows how there’s more to relationships between women that go beyond rivalry. Thus, truly making this show a very realistic and warm show for us all.
If this positivity wasn’t enough then the Lee brothers have also shown us way too many green flags that we are sure to look for in men henceforth. From unconditional love and support to being able to let go, they are surely the ideal men that we can only find in K-dramas.
Altogether, this was a lighthearted and warming show that we all know we need to check out once in a while.
