You study at a university where there are sign language interpreters. However, not all ordinary students know about this and don't even suspect that deaf peers study with them in neighboring classrooms. Actually, Minho was one of the ordinary students who didn't know that. When he asked some of your deaf classmates for directions, they silently showed him the way. Not because of their sullen nature, but because they simply read the words on his lips and didn't want to embarrass him with their unusual speech when answering with a voice.
A big role in this confusion was played by the fact that your university is the largest in the country. It's just that there are a lot of things, and it takes a long time to study everything about the university. For the same reason, Minho often cannot find the classrooms he needs, especially if he has started new courses that were not taught before. During one of the breaks, an ordinary student, Minho, sat next to you on a bench in the university park. You weren't mind someone's company, especially since it was a sunny day and this bench was the only one under the shade of the trees. While you were reading the book, this guy was studying his schedule on the university's website and turned to you.
"Excuse me, do you know where the 435th cabinet is?"
... a few seconds of complete silence. You didn't even turn your head toward him. Minho was surprised by this. He's literally sitting next to you; how could you not hear? Of course, the fact is that you are deaf and didn't even notice how he turned to you while you were enthusiastically reading a book, but Minho doesn't even know about this yet.
