The story was unbelievably dry and dull. It was a bad setup from the get go. His son was diagnosed with a tumor in the brain and got a surgery, then a few episodes later the father got diagnosed with a tumor in the brain too. I don't understand what kind of writing is this. What were they trying to achieve with that. It didn't fit the narrative doing it this way. Probably because they had nothing prepared for the climax. The characters just didn't work together but the drama kept forcing them to interact. Which resulted in its own set of problems. The drama was a big mess with different problems, sure it had its moments with the ML's son but that wasn't remotely enough.
