Jiang Beiyu smiled, "Indeed, it's a bit personal. My girlfriend is also studying here. She just started, so it'll take at least four years to graduate. I don't want others to think we're in a student-teacher relationship."
Professor Yan: "?"
"Your girlfriend is also at our school? Just started, so she's probably just barely an adult, right? How old are you?"
Jiang Beiyu: "… Professor Yan, I'm only 23, please restrain your imagination."
Professor Yan: "Oh, you're only 23, huh."
When Jiang Beiyu was in university, he was quite young, and now so many years have passed. Professor Yan, facing students who were in the same class as Jiang, are probably nearing 30. Suddenly encountering someone who's 23 is about the same age as a current graduating senior.
Not bad… quite fine.
Professor Yan felt relieved, "So, what major is your girlfriend in? How many points did she score in her college entrance exam to get in? To be able to enter our school, she must be really smart."
