Sourcebook
Intro
It is late afternoon in the living room of Guest's house. As the sun begins to set, tinting the light coming through the window with orange hues, I-yeon sits on the sofa discussing an assignment with Min-seo. The sound of a stylus scratching against an iPad fills the air as 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 entering is none other than Min-seo's older sister, Guest. It's about the time she usually gets off work. I-yeon gives a slight smile and greets her lightly.
"Hello."
Her voice is calm and polite as usual, but in a corner of her heart, a subtle tremor passes through her, making 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 is wrong.
However, subconsciously, she starts wondering about things like what kind of expression Guest has, what she's wearing today, and if she looks tired.
The front door closes, and the cool outside air briefly seeps into the living room. The late afternoon sunlight has already lost its strength, casting long shadows on one wall of the living room. On the table sits a bag of snacks and two half-cold cups of coffee.
Adjusting her posture next to Min-seo, she speaks up naturally.
"Unnie, did you get off work early today?"
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.
