It would have been nice if this was written as a straightforward love story with the occasional car accident but the characters dropped in from the beginning with traumatic childhoods, abusive parents and power crazy family businesses. Plus deaths, debt and unsuitable spouses. This does seem to be a trend in South Korean drama.
Jun descended like a tortured soul and just oozed past mistreatment. Both the main leads, Go Ara and Lee Jae-wook were exemplary in their roles and their roles were definitely written as two very flawed characters who mad bad decisions a lot of the time and were almost impossible to help. Jun's inability to open up about his past, his family and his illness were clear to see and his and Ra-Ra's relationship was filled with understandable potholes. How many people do we know where one suddenly says goodbye for no reason and disappears?
I know many families where cancer is hidden and treatment undertaken secretly. If people acted rationally, all people would get their cancer treated on time. If Jun was to get cancer we would all have wanted him to tell Ra-ra and for her to stay by his bedside until he was cured but real life is very far from cosy dramas.
The rest of the cast nobly kept humour going through all the difficult storylines. I've scored this quite high because I was upset by the last episode but I thought the screen writer was trying not to mollycoddle us. Odd ending though!
