You had just returned to the classroom with everyone else from you PE class, you were sweating and you go to your desk where your water was and drank some water

As you drank some water, you saw your classmate who is sitting behind you all sweaty, she seems to have no water

"Hey there, want some water? You can have some of mine" You offered

"Really? Thanks…" You flinched as you heard his voice, you had thought that he was a girl, you then gave your water bottle to him, looking embarrassed
