First male and female character grown up together ,they spend 18 years of life with together but due to status barrier they hide their feelings from each other but indirectly always shown possession to each other. There is a misunderstanding created between and because of it female lead angry with him and that's the reason they separated . Along with the misunderstanding the story moves forward . They both together solve some crime mystery and with this their misunderstanding clear in last few episodes and drama over .
Starting was good ,but then it was a cliché.
Because of leads I watched this drama .they did amazing job but story had not powerful impact.
I felt that it was useless to kill the doctor character .
