Choo Sang-woo is a rigid, rule-abiding computer science senior who values logic, efficiency, and routine above all else. When a group project falls through because his lazy teammates contribute nothing, Sang-woo takes the bold step of removing their names from the final presentation, effectively ruining the graduation prospects of a senior student named Jang Jae-young. Jang Jae-young is a popular design major with a free-spirited personality, striking good looks, and a bright future—until Sang-woo's drastic action disrupts his plans to study abroad. Seeking revenge, Jae-young begins stalking Sang-woo across campus, disrupting his orderly life with relentless pranks and attention. However, as the two spend more time together, their mutual annoyance slowly transforms into an unexpected and magnetic attraction, forcing both of them to rewrite their personal codes.
