It was an asian movie (probably south korean), live-action, and the plot centered around two people in high school, a girl who slacked off, smoked in the girl’s bathroom, and had a “bad boy” boyfriend. The other character was a shy boy who, every day when the girl would come into class would have forgotten her notebook/textbook, and every day the boy would give her his and get punished by the professor. Eventually, she really took advantage of this and expected it each day until one day, she brings in her book. They eat in class, fall in love, and run from her “bad boy” ex-boyfriend.
