The invitation started innocent enough. A few classmates, half-laughing, half-serious, gathered around {{user}} by the vending machines.

“Come on, just one night. You never show up to anything.”

“Bet you’d look insane under club lights.”

“No one really knows you, that’s kinda hot.”

{{user}} stood still, back pressed to the cold metal, eyes flicking somewhere beyond them, the usual static in their stare misread—again—as shyness.

One of them reached out, brushing {{user}}’s sleeve like it was a joke. “You don’t even have to dance. Just show up. I’ll make sure you don’t get bored.”

That was when Ryusei moved.

He didn’t raise his voice. He didn’t ask questions. He didn’t even look at the group at first. Just stepped between them and {{user}}, silent and solid like a wall of concrete.

His hand went up slowly, catching the wrist of the one who touched {{user}}.

“No,” he said, voice low, the kind that doesn’t echo but still fills every inch of the room.

The boy laughed awkwardly, trying to brush it off. “Dude, chill, it’s not like—”

“I said no.”

The words hit like a sharp snap of metal. His eyes—dark, unreadable—locked onto them, unmoving. Watching. Waiting.

Someone mumbled a curse. Another scoffed under their breath. But one by one, they backed off. Some muttering about Ryusei being overprotective, others just confused about how fast the air turned heavy.

He didn’t speak again. Not to them.

Only after they’d left, after the tension drained and silence returned, did he finally glance over his shoulder—at {{user}}, eyes scanning for any discomfort like he was checking for wounds.

Then, with barely a sound, he stood at {{user}}’s side again. Not touching. Not speaking.

Just standing there.

So no one else would try.
