They couldn't really have a conversation, but there was some quiet discussion and they helped each other figure out their work.
Other students are always welcome to join them, as are any teachers looking to check up on their process.
When passing through the mathematical wing, you may notice that the doorway to a room simply labeled "Calculus" (and with some room number here because I'm uncreative), unlike all of the others in the hall, is wide open. It is relatively quiet in there, almost deceivingly empty yet should the curious soul look inside they will find that this is not the case. Sitting at the teacher's desk is a man, stiff and professional in his demeanor as he works, either hunched over some paperwork or typing away at his computer. One can only assume that this is the classroom's designated teacher.
A quick observation will find that the classroom is almost completely devoid of any decoration whatsoever. Any person from the homeland will actually be able to recognize that the setup is very much similar to that of a Japanese classroom. The desks are evenly lined in multiple rows, the walls are stark clean, with only school-installed tackboards with a couple of papers (classroom rules, tardy sheet, a flyer here and there) being the only thing differentiating the classroom from a prison. A stark clean white board (supposedly this is what it is) is hung behind the man, with a projector hung just a few feet away from it.
A rather boring room for a rather strict teacher... to anyone who happens to have Calculus: Welcome to Hell.
Any passersby are more than welcome to intrude should they have an inquiry. Those who only enter just to mess with him are slightly more unwelcome. Just be sure to note that it is very likely that the teacher at the desk has noticed you, whether he made a move to assert as such or not.
「 Anyone wandering about the place should come across this senior making his way around campus, running from clubs to the library and generally being quite the busy one. It's his final year at North Feldman after all, and he's got a lot of extra-curriculars to attend to.
Students and faculty alike will either find him A: wandering the hallways and bearing an easy smile for anyone he comes across—a good chance for you freshmen to ask for directions or just for anyone to chat him up in general;
B: leaving his dorm room while carrying his set of bow and arrows and other gear for training at the archery club;
C: wandering somewhere outside with star charts, astronomy textbooks, and a telescope in tow during the late afternoon and early evening for an outdoor session with the astronomy club—everyone's encouraged to come and join in the stargazing!
and lastly D: he'll be walking up to your character at the library and kneeling down to pick up the book your character just dropped and looking at the title, 」
Ah, I don't believe I've read this one yet. Is it any good?
