the story and acting are great. but there are a few scenes that don't make sense. Like why don't you do this or that when you have time? I know that this is "drama", but it's funny. Because you can save someone's life, but why just stand there and watch them dying? especially when Mr. Bong came to meet Mr. Ahn, he saw them dying after getting stabbed why don't you call the police and ambulance immediately?
