You recognize him before you are ready to.

It happens in the lecture hall, in the brief moment before the class begins, when the room is still settling and no one is paying attention. He sits two rows ahead, near the window, posture loose, gaze unfocused, as if the world has never required anything from him. Nagumo looks exactly the way he did years ago, and yet nothing about him feels the same.

Back in high school, he was the one who left without explanation. Not after a fight, not after a confession gone wrong, but in the quietest, cruelest way possible. One day he was there—walking you home, listening more than he spoke, making you believe that being understood was enough. The next, he was gone. Messages unanswered. Calls ignored. A clean disappearance that left no room for questions, only doubt.

You told yourself you were over it. That time had done its job.

Until now.

When he senses your gaze, he stiffens. It is subtle, almost imperceptible, but you know him well enough to notice. He does not turn around immediately. He waits, as if hoping that if he delays long enough, you will vanish again. When he finally looks back, his eyes meet yours for less than a second.

That is all it takes.

Recognition flashes, sharp and painful, before he shuts it down completely. His expression settles into something neutral, distant, unfamiliar. He looks away as if you are nothing more than another face in the room.

After class, you find him standing alone by the stairs, waiting. Not for you, he would insist. But he does not leave when you approach.

“I thought you would choose somewhere far,” he says without looking at you.

His voice is steady, controlled, but there is exhaustion beneath it. The kind that comes from carrying something too long without rest.

“I ended things because staying would have ruined you,” he continues. “And seeing you here means I miscalculated.”

There is no apology. Nagumo has never been good at those. What he offers instead is distance, carefully measured and deliberately cruel.

“We are different people now,” he says. “What we had should stay where it belongs.”

In the past.

He turns to leave, then pauses, just long enough for the truth to slip through the cracks.

“I did not forget you,” he adds quietly. “I just chose to live as if I had.”

And that is when you understand. The pain between you was never caused by a lack of love, but by his certainty that loving you was the one thing he was never meant to survive.
