Autumn Calculus

Our protagonist, a dedicated and slightly introverted mathematics major, has her life meticulously planned out. Every moment of her day is scheduled for study, coursework, and tutoring sessions, leaving little time for socializing or fun. She's determined to achieve her goals, but as autumn sets in, so does an inexplicable sense of loneliness.

Enter her sunbae (upperclassman) in the form of a relaxed, seemingly carefree arts major who has an annoying habit of popping up exactly when she needs him least. He's late for everything, has a thousand unasked-for opinions, and somehow sees through her "I don't need anyone" facade. Despite his teasing, he offers a fresh perspective on life outside of academics, challenging her to loosen up and experience more of her university days.

What starts as a simple annoyance blooms into something deeper as she realizes he may be the exact variable missing from her otherwise perfectly structured life.
