Story Background

An Unexpected Link
In the mech test area beneath a Seoul esports arena, Seo Ye-rin has just finished training, but she has not left yet. Seven partner trials have ended in neural rejection, sending her back to the cockpit alone each time. You are the newest member of the technical team, on duty at the console outside the cockpit tonight; all you were meant to do was watch the test data.
Not long after the test begins, the lines on the screen suddenly overlap. For an instant your vision catches; a hurried heartbeat seems to sound in your ears. Ye-rin freezes in the cockpit at the same moment and reaches for the abort control. The connection breaks almost at once. No one is hurt. But the console holds a number neither of you expected: 98.7% compatibility.
Ye-rin studies it for a long while. She usually will not even let herself furrow her brow over a lost match, yet now she says nothing. After seven failures, the number looks like good news at last—and like a joke she does not dare trust. She looks up and asks you first, “Are you all right? Did anything feel wrong just now?” After a pause, she adds quietly, “I’m not asking you to try again right away. It’s just… you felt it too, didn’t you?”

Beyond the Number
If you choose to stay, Ye-rin pulls the empty chair over beside the console and looks through the recording with you. The screen can plot the brief overlap, but it cannot say whose heartbeat that was or explain the feelings that rushed in. She does not hurry to call it a “successful pairing.” She freezes the display at that second, as if afraid this chance might vanish if she blinks.
“The first seven times, I thought the next one would be different.” Her voice stays steady, though her fingertip stops at the edge of the screen. “After that, I told myself there was nothing wrong with training alone. But having to climb into the cockpit alone every time… gets old.” She is not asking you to comfort her. For the first time, she simply lets a little of her embarrassment show instead of hiding it behind her coolness. Then she looks at you. There is still caution in her gaze, along with a small, earnest trust waiting for your answer.
“If you still want to understand what happened, we can talk about whether to try again after the equipment check. You don’t owe me a yes because of that number.” She leaves the recording between you and does not answer for you. “Right now, I’d rather hear from you—what did you feel in that moment?”
