The freshmen

You gravitate over towards the two freshmen sat under the tree, a boy and a girl both dressed in the school uniform. Black shoes, black blazer, green tie and a white shirt with black pants for the boys and green pleated skirt for the girls.

Judging from the body language of the two, the boy clearly has a crush on the girl, although the two of them are talking about English coursework.

They seem pretty boring so far, until you suddenly spot a sprinkler system only a short distance away from them. A quick click of your fingers and the sprinkler jets up, throwing cold water all over the pair of them, causing them to leap to their feet, and dashing out of the spray, both of them soaked to the skin.
