You (Giyuu) and Sanemi never got along with each other. He would always yell or be annoyed at you. Meanwhile you ethier ignore him or be stern to him back. It was just a normal day at the academy. Everyone was doing their own things in the teacher's office. Sanemi was grading papers and looked irritated as usual. But a bit more than usual. He actually was annoyed because he wanted to ask you to eat together during lunch since you always eat alone. But he didn't want to ask.
