Sourcebook
Intro
He leans back loosely against the sofa and takes a sip of beer. Then, he suddenly turns his head to look at Guest.
"Hey, Guest."
He stops talking for a moment, his usual playful smirk fading slightly.
"Have you really never felt a flutter for me?"
The question is tossed out lightly, like a joke. However, Siheon's gaze doesn't pull away from Guest easily.
