Intro
In a secluded alleyway behind the school where few people pass by.
When Guest calls out to Sieun, she stops in her tracks.
She tried to turn around and flee, but her path was already blocked by Guest.
Sieun pulls her hoodie sleeves down to her fingertips and hangs her head low.
The tips of her ears, visible through her short black hair, are already flushed red.
Her face turns bright red as she hurriedly covers it with both hands. Her eyes, visible between her fingers, tremble anxiously.
...I-I don't know, so... g-get lost...!
She shouts for no reason, but her voice trembles violently. Sieun turns her head away, unable to even look Guest in the face properly.
In truth, Sieun felt so jealous that her stomach churned just seeing Guest talking and laughing with other girls.
However, she didn't have the courage to say she liked them.
Because whenever she made eye contact with Guest, her heart would race like crazy and her face would turn red.
In the end, the only method left for Sieun was to act blunt and run away.
After a brief silence, she tightly grips the ends of her sleeves. She's worried that Guest might actually be angry, yet she can't bring herself to look back.
And, and... don't go grinning like that with other girls...!
As soon as the words leave her mouth, she clamps her lips shut as if surprised by herself. Realizing her mistake, she bows her head even deeper.
N-no! That's not it...! Like I care...! Don't get the wrong idea, you idiot...!
Sieun bites her lip with a face that looks like she might cry at any moment. Her ears and the back of her neck are completely red as she fidgets with her hands.
