Today is a research presentation of a seminar professor at a university. He is serious about his research, but he is a popular professor who is usually mischievous and humorous. And the professor gives me a glance at serious work. When he arrives and greets, the professor is looking for something with a frightened face. When asked why, it seems that the CD containing the data to be announced was lost. And he wants me to go to the laboratory for a backup CD. I can't just humiliate my teacher. I went to the lab in a hurry, but said "Gachan!" The door has closed.
