When a notorious troublemaker sets his sights on the school's top academic achiever, her desperate plea for protection backfires spectacularly—his own father intervenes with unexpected fury, forcing him to abandon his pursuit entirely. Years pass, their paths diverging as she climbs toward her dream of Tsinghua University, only to discover that he's been quietly following the same ambition all along. A second chance encounter reveals that his youthful mistakes were merely the beginning of a transformation neither of them saw coming, and that sometimes the person who once terrorized you holds the key to your greatest love story.
