"Yah, Hyunwoo-ah!" Soohyun shouted from afar. 

With music blasting through his headphones, Hyunwoo continued walking briskly. The wind blowed his fringe a little so he fixed it and looked up. 

"The clouds are beautiful today." He thought. 

"Yah, Lee Hyunwoo!" Soohyun tried again.

Seeing him approach the bus stop, Soohyun began picking up his speed. Then, Hyunwoo started running too. The bus was arriving, he realized. Soohyun found himself sprinting after the boy who was sprinting too. Then, he halted to a stop out of a sudden. Images ran through his mind, and he saw himself on a rooftop. He was wearing a ridiculously ugly green outfit, he noticed.There, he was standing by the edge and he said, 

"This boy is really fast. "

Soohyun panted heavily as sweat trickled down his forehead.

"Yah. The driver was staring at me when I alighted right after I boarded...." Hyunwoo grumbled.

Dissatisfied that he was not getting any response, he waved his hand before the dazed boy. When Soohyun looked up and was met with his best friend in uniform, bag pack and headphones on, he stared hard. 

He thought he looked strikingly familiar and it was odd to think that way. 

'Lee Hyunwoo, my childhood best friend. How can he not be familiar?' Soohyun thought. 

"I think I'm weird." Soohyun commented out loud.

"You sure are." Hyunwoo concluded.

As they walked on, Soohyun found the images haunting for he couldn't understand what they were.

He was sure he had never been to any rooftop like that.
