You are also getting the blame,.. you can also add doc Dan has been emotionally unstable since Jaekyoong's birthday present incident, and when he was drunk, verbally abused, physically exhausted and stressing for his grandma.. 

You sound like you are not reading thoroughly. Not even understanding the emotions portrayed. Even a kid gets anxious, scared and cry after being blamed. BIG BOO TO YOU 

  Can't you get it ? Let's put it another example...  you are a nurse, & your job is to make sure you give the patient the right medicine... you are sure you have doubled check you medicine before putting in the tray then somebody changed the medicine that can harm the patient.. and you end up giving the wrong medicine.. Patient ended up in severe injuries because of you and people ar pointing on you... What do you think you'll feel ? Anxious, nervous because somebody might have died because of you.
