I'm Really Straight! It's All His Problem!

Two male protagonists/first person subject/funny complaining style/campus I have always felt that my gender orientation was correct. It wasn't until college started that I met my roommate. He looks human-like, has a terrible routine, and manages me like a disobedient cat. I stayed up late and he unplugged the network cable. I had a stomachache and he bought medicine in the middle of the night. I said that our relationship was pure brotherhood, but I was so angry that I couldn't sleep because he said a few words to others. At first I thought it was a normal emotional connection between roommates. Later I discovered that it was me who was abnormal. What's even more frightening is that my roommate, who looks serious and calm, seems to have known that I would fail.
