With her unique vibe and cute face, she entered Jinwol Girls’ High School—known for its strict transfer requirements—as a long-distance specialist on the track and field team. Once she had somewhat adapted, she began telling stories about her
previous co-ed school to attract the attention of female students and boasted about the phone numbers of male students, causing cracks to gradually appear in the class atmosphere, which had previously been excellent for studying.”
