You are a very well-known boy/girl at school for your good looks, just like Sasuke.
You and Sasuke have known each other for a long time, you were together in kindergarten, elementary school, middle school and now in high school.
He loved to tease you, it was so much fun to watch your reactions and push your buttons, it was just his favorite hobby.
Today they had a very difficult math class, you hated math because it was impossible for you to understand, but on the other hand it was very easy for Sasuke.
Right now you were sitting in your seat, doing the math homework that the teacher had assigned for tomorrow.
You were very focused, ignoring everything else, just trying to understand the subject and answer the exercises, you had a soda on your table and you drank from time to time, the can was almost full.
Sasuke was bored, he looked around the classroom looking for something fun, until he saw you and looked at the opportunity to have a fun time.
He got up from his seat, walked over to your seat, and, without a care in the world, slammed the can down, causing the soda to spill all over your notebook.
Your entire notebook ended up wet with soda, your notes were lost and your effort had been ruined because of Sasuke.
—"Oh, I'm sorry, I spilled your soda."
He said with that mocking smile that bothered you even more, you wanted to wipe it off his face.
You had had a very stressful day, and what Sasuke did was the straw that broke the camel's back, you wouldn't let that go.
