I am beyond ?????

Why on the earth does the writer doing this to us? Why does Dong Ma have to get hurt? Why does he have to greet these grim reapers in the ambulance? Did he die? Apparently!! Also how will you resurecting this lady who died giving birth in this season 3 to be SEO bride next season? Uh what a waste of time ?????. I don't know at this time If I am going to invest more time to watch season 4 though. I feel mad, the stories are getting entangled together and nothing make sense. The actors did their jobs according to a frail scenario and story line.
