He does, very much so. You are in for a ride of how the relationship progresses in the later chapters lmaooo. As for the hand cover, it just means that the professor is a very die hard for his mission in life to seek for the true sound, even at the expense of his life. The fact that he covered Graham during the accident to ensure the safety of his student’s hands sounded extreme to him atm hence by covering it, Garam will use him accordingly to achieve it as if the professor doesn’t even care abt his own life, why should him you know?

Hi so i can't really get the meaning behind where Graham is covering the professor wound while saying that he's going to use him? I mean does it mean that he actually deep down cares about professor and the hand is a symbol of him denying it?
