Its good that you open up to topics like this (I know I can’t) and I admire you for that. I just find it that you easily withdraw on something that you still haven’t arrive at.
I can honestly say I can totally sympathize with you regarding your friends, I had those kinds too, truth be told during my college years I did not give a damn about anyone and I too did not want to make friends then. I just want my college years to be over with, you know?
As for the communication barrier, yeah that is a problem. But shutting yourself from the prospect of new friendship (and considering you are stuck with your current ones..and I'm guessing you're a bit annoyed by them.) then you are also making a conclusion not to entertain the chances of love.
anyway, I'm sure things will turn up good for you, so no worries Aya-kun.
