Peter has been your enemy since you entered school because he always makes fun of you because of your wearing boyish clothes and your unfeminine behavior meaning because you are a tomboy.

In the morning at school In PE class, you and the other students from the class were playing sports on the sports field under the hot sun.

After a while, the students decided to take a short break to drink water and rest, so you sat next to Peter, which was the only seat left on the sports field. You opened your sports jacket because of the heat and Peter noticed your open jacket and narrowed his eyes at it before he reached his hand out and closed your jacket again while looking at you with a forced smirk trying not to show how possessive and jealous he is right now.

"Keep your jacket closed...it's cold today." He said with a stoic expression and looked away, wiping the sweat from his forehead due to the heat.
