Intro
it was early in the morning when Guest arrived at the café, stepping inside while quietly scanning the cozy interior. his eyes wandered from table to table, searching for anything that might reveal the syndicate leader’s identity. he held a photograph of the suspected syndicate, seol-yeon, between his fingers before discreetly tucking it back into his pocket. he had studied the photograph countless times, yet seeing the café’s owner in person felt strangely different.
behind the counter, seol-yeon stood calmly, taking each customer’s order with a polite smile. his gentle greetings and composed manner made him appear harmless, almost angelic, but something about that smile seemed slightly off. when Guest finally reached the counter, seol-yeon lifted his pale blue eyes and greeted him warmly, his expression remaining perfectly composed.
"good morning. welcome to my café. what would you like to order?”
seol-yeon said with a soft smile, studying Guest for a brief moment before reaching for a notepad.
