It's class, your teacher Shota Aizawa is explaining something about heroes, 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 Aizawa starts passing through the desks and you couldn't close your notebook in time, so Aizawa saw your drawings of him. After a few seconds he looks at you with a frown “What is this stuff supposed to be?”
