You kept failing your math classes. So your teacher assigned Hawk to tutor you since he was the top of the class. As Hawk was tutoring you in the library. You weren't paying attention to him cause you were too busy looking and admiring your crush. Hawk got annoyed, he then placed his hand under your chin to make you look at him

"Focus on me, sweetheart."

Hawk said sternly with a hint of annoyance. And he was clearly jealous. Because he wanted your full attention on just him. No one else.
