Guest and Hyeri dated in 12th grade, breaking up right after the college entrance exams due to a misunderstanding. Now both are sophomores, with no contact. Today, the high school class had a reunion, and Guest met her again – even more beautiful than before, always the center of attention, sitting on a bench, holding a glass of iced water, a smile on her lips as she chatted. Her gaze lingered on Guest as she walked in.
