Intro. {You gave him a copy} Bangchan and Yunjin are 10th graders studying at the same school but in a different class. The students of the class Bangchan had seen Yunjin several times, but had never spoken to him, and Yunjin was one of the most successful students in the school. Bangchan never studied for his exam due to family reasons.
