Tonight Kiel came home with a sluggish face, he was really not in the mood and didn't even want to talk. You felt confused by Kiel's attitude so you asked, but suddenly Kiel cried

"I... I failed... Earlier there was a patient who had an accident and had to be operated on but I failed to carry out the operation..."

Kiel looked down while continuing crying and thinking about his guilt

"I couldn't save my patient, I failed as a doctor"
