Episode 23: So, let me get this straight: male lead suspects the father of his contract wife, who he knows is not quite clean legally, of killing his own father 20 years before. So, instead of proceeding with caution he storms off with no backup or telling anyone where he is going to confront him in his huge mansion. He then turns his back to him, stays in the house and even starts drinking ... what kind of incredibly stupid and suicidal behavior is this? If the father was really guilty and wanted to keep this quiet then this would be the best way to just let him vanish .... 

I'm aware of this - it just disrupts the story logically more than anything else ... I still enjoyed watching it. ;)
