(3)The professor was talking about a topic in class
(4)I was 27 years old
(5)And as soon as we were about to continue
(6)I didn’t miss the timing when I was in the front class
(7)Oh, then it was last year
(8)When I said that, the professor couldn’t help but smiling
(9)You protected Umji regardless of seniority
(10)Surprisingly, a story from 10 years ago
