Well, these things happen. In my school, we have this canteen that's behind the GS Building. The departments around are music, arts, and then we have the General studies building. So if anyone is offering GS courses, art courses and music, we will most likely always meet at the canteen and it's environs.
You can assess the situation and see if your departments or classrooms are close by or something. If not, then it could just be a coincidence and who knows, with time maybe you both can make a meaningful connection but in all, there's no harm in being vigilant for the meantime.
funny is that our departments and classrooms are not the same place. Also we meet more outside of school. I noticed that his house is not far from my place which also contributes to us meeting more often. But there are a lot of people living close to me and we don't meet like that on a random as I do with him.
Ohh, that's it.
Well, whatever it is or it will be, like my mum always says, time will tell.
