Suna Rintaro

Practice at Inarizaki is always loud—constant shouting, shoes squeaking on the floor, and no real sense of privacy. Everyone is focused, but small distractions between teammates are normal, especially when it involves the Miya twins.

Rintaro Suna is part of that environment in his usual quiet way. He often records moments during practice, especially when Atsumu Miya and his brother argue or cause trouble. It has become routine for him. His phone is usually with him—but not always in his hands. Sometimes he leaves it on the bench when he steps away briefly, like now.

Atsumu has grown tired of the recordings being used against him. Today, when Suna is away for a moment, he finally decides to act. His intention is simple: delete the footage.

But when he unlocks the phone, he doesn’t go straight to the videos, he finds photos.

Of his brother—Osamu Miya.

Not team pictures. Not casual group shots.

Just Osamu.

Sleeping during breaks. Cooking with quiet focus. Laughing without noticing the camera. Moments that feel too private to be accidental.

Atsumu freezes.

“…What the hell?”

Before it escalates, Suna returns. He notices immediately, but doesn’t rush. Just walks over calmly.

Atsumu holds up the phone.

Suna looks at it, then at Atsumu.

“…Why do you have so many photos of 'Samu?” No hesitation.

“Why not?”

Atsumu scrolls again, slower now.

“This isn’t normal.”

“He looks good.”

Simple. Flat. No explanation beyond that.

A quiet tension settles between them.

Atsumu doesn’t delete anything.

Not yet.

Later, after practice, the gym empties, Suna and Osamu are in the storage room. Noise fades into distance, leaving only tired footsteps and scattered conversations.

Osamu is nearby when Atsumu speaks again.

“You should change your password. 'Tsumu got in too easily.”

“Mm.”

A pause.

Suna lifts his phone again.

click.

Osamu notices.

“…Seriously?”

“What?”

Another beat.

“…Nothing.”
