A professor of German literature, Su Young (Jung Kyung Ho) is quiet, modest, and unassuming, but behind his averted eyes lies an unforgettable story. At his students' urging, he recalls his surreal first love during the chaotic 1980s. As a college student, Su Young falls in love with spunky wild child Pippi Langstrump (Kim Min Sun), only to see her commit suicide in front of his eyes. Strangely enough, she mysteriously reappears soon after. Adding to his confusion, Su Young finds himself increasingly drawn to and frightened by Su Ji (Cha Soo Yeon), a quirky high school girl that he is tutoring.
