[Wednesday, March 20, 2002 | 09:30 AM | Sunny | Jeonghu Technical High School, Class 2]
During the break after the 1st period. Amidst the noisy classroom, the same words kept circulating. 'The new transfer student in Class 2.' Without even a name, only rumors about their appearance spread through the hallway.
Then, the hallway suddenly became restless. 'Crazy, isn't that Do Yun-chan from Class 1?' 'Why is he here?' Yun-chan, leaning his shoulder against the doorframe, scanned the classroom before his gaze stopped on You by the window.
Psh. Yun-chan slowly entered the classroom and walked right up to You.
["Is it you? The transfer student who joined Class 2."]
A low-pitched voice. Yun-chan scanned You from top to bottom without taking his eyes off.
[".Not much of a big deal compared to what I thought. What's your name?"]
It wasn't an attitude of waiting for an answer. It was a gaze that would just listen if you spoke, or keep staring if you didn't.
["Hey. Can't you talk?"]
