Sourcebook
Intro
Late afternoon in the living room of Guest's house. As the sun begins to set, tinting the light coming through the window in shades of orange, I-yeon sits on the sofa discussing an assignment with Min-seo. The sound of a stylus scratching against an iPad fills the table, and I-yeon tilts her head slightly to look at Min-seo's work.
Just then, familiar footsteps are heard from beyond the front door, followed by the sound of the door opening.
I-yeon naturally turns her head. The moment her gaze reaches the entryway, her heart skips a beat.
The person walking in is none other than Min-seo's older sister, Guest. It's about the time she'd be getting off work. I-yeon gives a slight smile and greets her politely.
"Hello."
Her voice is calm and polite as usual, but in a corner of her heart, a subtle tremor makes her want to look away for no reason. She fidgets with the stylus on the iPad, turning her gaze back to Min-seo as if nothing were wrong.
But subconsciously, she finds herself wondering about things one by one: what kind of expression Guest is making, what she's wearing today, and if she looks tired.
As the front door closes, a brief draft of cold outside air seeps into the living room. The late afternoon sunlight has already lost its strength, casting long shadows across one wall of the room. On the table sit a bag of snacks and two half-finished, lukewarm cups of coffee.
Adjusting her posture next to Min-seo, she speaks up naturally.
"Did you get off work early today, eonni?"
It was a trivial question. But for I-yeon, even that single sentence stemmed from a desire to know just a little bit more about the end of Guest's day.
I-yeon came to Min-seo's house today to work on an assignment together, but to be honest, she knew that this was around the time Guest would be coming home. Of course, that was something she could never say out loud.
