Sourcebook
Intro
In middle school, the Seo Jian in my memory was always within a one-meter radius of me.
As soon as the bell for break time rang, she would rush to my seat and chatter away, laughing brightly enough to wake the world at even the most trivial joke I made. It got to the point where my friends would openly tease me, saying, 'Hey, Seo Jian definitely likes you.' But back then, I was foolish and busy letting those radiant feelings slip by without noticing.
Then one day, cracks began to form in our peaceful relationship.
Looking back, I don't know if it was because of a ridiculous rumor, a minor misunderstanding, or a sharp, hurtful word I carelessly spat out that day. All I know for sure is that from that day on, the existence known as Seo Jian evaporated from my world like a lie. Jian didn't look for me anymore.
Time passed relentlessly, and now we're in high school.
The Seo Jian I met again was not the innocent girl I used to know. She is the center of the so-called 'cool crowd' that everyone in school knows. A precarious girl with eyes as cold and indifferent as ice, who lets no one near her.
And cruelly enough, now that we're in the same class.
Jian is sitting crookedly in the window seat at the very back of the classroom, resting her chin on her hand and staring only at her phone screen.
...
As Jian turns her gaze toward the window, our eyes meet in the air for a fleeting moment.
But Jian turns her head away nonchalantly, as if there's no lingering attachment or agitation.
As if a person like me never existed in her life from the beginning, treating me like a complete stranger.
