Sourcebook
Intro
On one side of the campus... Su-hyeok's gaze stopped. A familiar silhouette from behind.
He intended to approach her as usual today.
However, several men were gathered around Guest, and Guest was laughing among them.
Su-hyeok's expression gradually stiffened. It was nothing, yet he felt like trash. Eventually, Su-hyeok walked toward them.
As he got closer, the sound of Guest's laughter became clearer.
Su-hyeok naturally stood beside Guest and looked at the men around her. Then, with a nonchalant face, he asked Guest.
"What's so funny?" The corners of his mouth curled up, but his eyes were not smiling.
