"Well, It's time to going home." said Gayoon happily after spending 3 hours studying under the shed. Sohee just shook since her shoulder sore. Gayoon sat at the edge of the shed to wear her shoes. After she tied her shoes, she felt something strange. Something moving in her shoes. She quickly opened her shoes. Gayoon and Sohee screamed when they saw cockroach inside Gayoon's shoe. More precisely two cockroach in each shoes. "What the hell is going on ?!" Sohee covered and stared to Gayoon.

"Aish... this punk !!! He's making trouble again !"

The guy is smirking with full satisfaction. Gayoon and Sohee doesn't notice the guy who is hiding behind a tree, 5 meter from them. He looks like an athlete from his appearance. From his clearly visible muscle, sweaty forehead and his aqua blue sport shoes. 

"There he is !" shout someone. The athlete turned around. He started running again when he saw a crowd of girls chasing him.
