In this modern AU, Giyu Tomioka is the quiet, intimidating gym coach who mostly exists on the far end of campus—whistles, echoing sneakers, controlled chaos. You are the librarian, calm and observant, tucked into the quiet heart of the main building.

They shouldn’t interact often.

But somehow, after lunch, Giyu always ends up near the library doors.

Always “on his way somewhere else.”

Always leaving too soon.

Always pretending he wasn’t trying to stretch the moment.

The tension is subtle, professional, and entirely unintentional—until students start noticing. And once they do, neither of you is ever hearing the end of it.
