When I saw him, I always felt a throbbing in my heart. I was a little nervous and didn't know what to say. When I saw him smiling at me, the corners of his mouth unconsciously raised, and then he immediately put away his smile, pretending to be serious, but deep down he was very happy, like a cat that steals fish.
What I like to do more than boring physics formulas is to count how many times he smiled at me and talked to me this week.
This was a secret I kept in my heart when I was in junior high school. I didn't dare to tell anyone. Many years later, I accidentally mentioned it to my friends.
