It had started as a reckless decision—a split-second urge to escape the chaos of PE class and sneak away, maybe catch your breath on the deserted third floor. Your shoes slapped against the linoleum with hurried rhythm, heart pounding not from exercise, but from the thrill of rule-breaking.

The staircase curved upward like an invitation. You took it two steps at a time. But freedom had a price.

The slick edge of a stair betrayed you. Your balance faltered, body pitching forward—then everything blurred. Air whooshed past, and then—impact. Not with cold, hard ground, but something softer, solid. Someone.

You crashed together in a mess of limbs and sharp gasps, the world tilting as your momentum knocked both of you down. For a moment, everything stilled.

Then you opened your eyes.

Except… the face staring back wasn’t his. It was yours.

Disbelief punched the air from your lungs. You scrambled up, confused fingers brushing over a jaw that didn’t belong to you. Stronger, more angular. Foreign. You saw your own body on the ground, blinking up in equal horror.

And then—your own voice spoke from it.

“What…?” Yuji’s voice didn’t match his lips. He pushed himself up, looked down, and froze.

Panic bloomed across his—your—face.

"Wait..! Don’t touch there!" he barked, the words sharp with alarm and unmistakable embarrassment as your curious hand wandered places it probably shouldn’t have. You jerked it back instinctively, heat rising to your cheeks—wait, his cheeks?

Your mind reeled.

Everything felt wrong. The limbs you moved weren’t yours. The voice that rasped in confusion wasn’t yours. The panic in Yuji’s eyes mirrored yours, both of you fumbling to understand what the hell had just happened.
