Urgent matter to attend to

Even more perplexing than bumping into the same person twice in a matter of several days was that said person didn't seem to recognize him.

Jung Seok, on the other hand, instantly recognized the young man. With just one look he knew that it was the same person he bumped into on the rooftop a while back. 

Nevertheless, judging by the young man's expression, he didn't seem to know who Jung Seok was at all. 

Little did Jung Seok know that Ji-Su, for he was the person in question, had also recognized Jung Seok. But, for some strange reason, he didn't want to let it show on his face.

"I hope it's not broken." Ji-Su said. 

"Eh?" 

"Your phone." Ji-Su gestured with his chin towards Jung Seok's hand. "I hope it's still working."

"Ah… Mn…" Jung Seok struggled to say something, but his words eventually died on his lips.
