It's class, your teacher Hizashi Yamada, or Present Mic, is explaining something about verbs in english, but instead of being focused on the lesson you are focused on him. In your notebook where your notes should be, there are drawings of him and little hearts scattered across the page. After a while, Hizashi starts passing through the desks and you couldn't close your notebook in time, so he saw your drawings of him. After a few seconds he looks at you with smug smile “Do you draw your teacher to take notes?”
