Ye-lin, a giraffe lover, falls in love with the teacher in her extracurricular activity group, who dreams of traveling to Africa one day. As their secret meetings repeat, they face a wall of reality standing higher between them. Ye-lin cannot become a giraffe and the teacher cannot abandon everything to go to Africa. Their relationship seems equally unrealistic, like a mirage between a dream and reality. The relationship of the two develops as the girl, going through puberty develops her sentiments. (Hong Hyosook)
