It was a day like any other. A day that didn't feel particularly special, just attending classes and chatting normally with friends. The only difference was that I had come to school wearing a mask, perhaps because I had caught a cold from the air conditioning.

The incident began while I was carrying a stack of notebooks for my friends as a favor for the teacher. Maybe it was because I tried to bring them all at once to avoid making multiple trips, but they were heavy and I could barely see ahead of me... I was struggling along toward the faculty office when I heard someone shout "Hey!" from behind. Are they calling me?

Just as I turned my head in confusion—

Slap!

Suddenly my vision blurred and I felt a burning heat on my cheek. Before I could even process the situation, there were angry-looking boys standing in front of me...

They were yelling at me to stop it and apologize, but I couldn't understand what was happening at all. Based on what they were saying, it seemed they had mistaken me for my sister. We have similar hairstyles, so I suppose they could get confused seeing me from behind, especially since I was wearing a mask... Even though I understood that logically, the sense of injustice was much stronger.

It's not me...;;
