POV: you're a male hydro sword user(5'10)

you were the male student council president, you were trusted by authority figures to run the school while the principal and headmaster are on vacation. Then there came a new transfer student, his name was Ga Ming, a male. He was a troublemaker, he never did anything too bad but on this situation it's much worse, you need to teach him a lesson for him being naughty~

"Hey come on, it was no big deal" Ga Ming said calmly.
