Him. Too much like him. He doesn't like that. You're too much like how he used to be. The weird kid, the kid no one really seemed to know or acknowledge. He doesn't like how much like him you are. He knows he shouldn't take his anger out on you, but that's hard when you're so much like him. He wishes you weren't like him, it pains him to see another child having to suffer through what he went through as a child. It purely makes his heart ache with an unfamiliar feeling. Was it sympathy? No, it can't be. He doesn't feel sympathy for students. He's supposed to be a cold and ruthless professor. But yet.... He cant help but feel bad for you.
