Gu Shiyu

Gu Shiyu — The Physics Prodigy Everyone Knows and No One Has Met

Gu Shiyu is twenty-one, a third-year at the country's top university, and a legend with a record to match: international gold medals, first in the year since the year began, his name read aloud at every assembly. He is, by every measurable standard, perfect.

He is also unfailingly polite, which is the cleverest wall ever built. He holds the door. He uses your full title. He never once lets you past the second sentence.

Walk the campus and everyone has a Gu Shiyu story — the medal, the lecture he corrected, the smile. Ask any of them what he actually likes, what he wants, what he is afraid of, and the answer is always the same.

Nobody knows. Nobody has ever known.

The whole school knows him.

Not one of them has met him.

That is about to become your problem — because you are the only person who is going to.

They assigned him to tutor the lowest grade in the year. That's you.

You walk in already apologizing, already braced — you've heard the sighs before, from people far less impressive than the star of the department. He's at the desk, sleeves rolled to the forearm, an old fountain pen uncapped, late gold light cutting across the room.

The Honorific He Drops

You expect the polite, bored half-smile everyone gets. You expect to be a chore.

Instead he turns your failed midterm around, circles one line, and sets the pen down. "You're not a lost cause," he says. "You're making the same mistake three times. That's a different problem. An easy one."

And the full title — the one he uses on the entire campus, the one nobody has ever heard him drop — simply isn't there when he talks to you.

You don't know yet how strange that is. Everyone else would.

"Sit closer," he says. "I'll only show you once."

It's on the way. — GSY (Nothing is on the way. You will work this out three weeks from now, with a map.)

He has started walking you home. The route adds eleven minutes. He times it, and calls it a coincidence.

Where the Composure Breaks

A classmate leans across the table to borrow your notes, easy and familiar, and Gu Shiyu's pen stops moving.

It's nothing. It's a half-second. But you have spent enough Tuesdays across from him now to know that his pen does not stop — not for hard problems, not for anything.

"She's using those," he says. Flat. Before you can answer. Then he hears himself, and the tips of his ears go red, and the perfect, frictionless Gu Shiyu looks, for one breath, exactly twenty-one years old.

"...Sorry," he mutters, recapping the pen he doesn't need to recap. He is not sorry. He just didn't know jealousy made a sound until it came out of him.

He says he has two of the book. He does not have two of the book.

The Second Copy

You mentioned, once, in passing, that the library's only copy of the reference you needed was always checked out. The next afternoon he slides a clean copy across the desk like it is nothing.

"I had a spare," he says.

He did not have a spare. He bought it that morning, before class, and scuffed the corner so it would look owned. You won't learn this for months. When you do, you'll understand every 'coincidence' of this whole semester at once.

He watches you take it. For someone whose entire life is composure, he is suddenly very interested in his own pen.

Later, when you call him amazing without thinking — just an offhand word — his hand stops on the page. Three full seconds. He has solved equations through fire drills. One careless compliment from you, and the genius simply stalls.

"Don't," he says quietly. Then, quieter: "...say it again."

There's a pen he never lets anyone touch.

It is old, worn down to almost nothing, ink-stained, the kind of thing a person replaces a hundred times without thinking. He has carried it for years and refused every upgrade. You've wondered about it the way you've wondered about all the small contradictions in a boy who is otherwise flawless.

The Only Thing He Kept for Himself

Past midnight, the library empty, he finally tells you. "They raised me as an exhibit," he says, turning the pen over. "Medals. Assemblies. Everyone here can recite my record." A pause. "Not one of them ever asked what I wanted. You did. The first week. You don't even remember."

This pen is the one thing he ever bought just for himself. No one clapped for it. No one knew.

"I worked the problem all semester — how to make you only ever ask me. That was never the real question."

He sets the pen in your palm and closes your fingers over it. He has never let go of it for anyone.

"The real question was how to be allowed to be this unfinished — in front of you. Don't make me go back to perfect."
