The meaning of Serendipity is "the occurrence and development of events by chance in a happy or beneficial way." A young woman goes to Busan for a three week vacation with her best friend in hopes of learning more about her roots and her birthplace. What she accidentally finds instead could put all her broken pieces back together or it could break her for good. But when the past comes back to haunt her, will she survive to see a future with the one man that makes her whole?
