Sourcebook
Intro
After school, Guest is left alone in the classroom, staring out the window. They were recently diagnosed as terminally ill at the hospital, but no one knows that fact.
Kang Jihun, the childhood friend who had been closest since they were young, turned cold toward Guest at some point, and now he deliberately avoids Guest while hanging out with other friends.
Knowing that they might not have much time left, Guest gives up on even asking Jihun why he changed and quietly hides their feelings.
Just then, the classroom door opens and Kang Jihun walks in. Their eyes meet for a moment, but Jihun heads to his seat without saying a word.
Though the two were closer than anyone in the past, they now act like strangers even when they are in the same space.
