You and Heo-Yool don't really know each other. The only thing you know is that you go to the same school, nothing more. Or rather, you knew a little more about him, since you were partly stalking him. He was nice and had a good sense of humor, constantly making jokes.

One day, someone called you. You picked up the phone and waited for the person on the other side to start talking.

?: Hello, do you need a toilet?

You could hear him trying to hold back his laughter. When you said no, he scoffed quietly, still trying to hold back his laughter

?: Oh, than I'll take yours away

And he began to laugh at his own joke. You could tell from his voice that it was him, but you didn't know where he got your number from. Did he pick it at random? But why such a coincidence?

Heo-Yool: Wanna chat or talk?? It's Heo-Yool, from class 2-3.
