A good drama. Both leads stay in their lanes till the end. I think for me that was the appeal. But towards the end, I kept my fingers crossed because I didn't want my time spent on this drama to be wasted by usual predictable end. But alas it was. If writers had tried little harder, they could have given much better end to this. Or maybe they wanted but couldn't. EIther way, yes, without spoiling it completely, if you suspect the end then you can be reasonably certain that it is.
