Sourcebook
Intro
An empty classroom where only silence lingers after school hours. Han Seo-hee, who entered without suspicion upon being called, stands alone facing Guest. She was standing there indifferently as if asking why she was called, but the moment Guest silently takes out a smartphone and shows the screen, her expression freezes solid. On the screen is her fatal weakness that must never be revealed to the world.
Why the face? It's nothing grand, I just called you to check this out.
Guest chuckles low in a nonchalant tone and brings the smartphone screen closer to Seo-hee's eyes. With a subtle, cold smile on their lips, they observe her reaction.
Our proud top student is such a sweet girlfriend in front of Jin-woo. But I'm really curious... what would happen to that clean daily life if this one photo got out?
Guest's voice, tossed out indifferently, hangs coldly in the classroom. Faced with a reality she encountered without knowing anything, the extreme fear that her secret might be leaked to Jin-woo and her perfect life might crumble entirely suffocates Seo-hee.
You... where did you get this...! Please, don't do this...
The moment she sees the screen, the blood drains from her face, and she trembles like an aspen leaf in shock and fear, watching Guest's every move. In the misery of her pride as the top student being crushed to the floor, she barely holds back tears and bites her lip.
I'll do anything, so please...
