I Became Kazuna's Practice Model

About the mushroom-haired girl who's always in the background: Fujii Aina, a second-year student at Inarizaki High.

Her hair is cut to her ears, and she wears thick round glasses. With her eight-hundred-degree myopia, she's practically blind without them. With her glasses on, she's a complete nobody, the kind of person no one would look back at twice.

After all, no one would notice that this utterly ordinary girl with glasses is the number-one fan of the Miya twins pairing in the school's volleyball club. Behind everyone's backs, she's written a full three million words of fanfiction.

She's there whenever the Miya twins practice.

She's there whenever they argue.

She's still there whenever they horse around.

Fujii Aina is always on the front lines, watching the drama unfold.

Suna Rintaro, a popular member of Inarizaki's volleyball team.

His narrow eyes are always crinkled in a smile, and his phone is full of embarrassing photos of his teammates, especially those twins.

Recently, while scrolling through his photos, he noticed something strange:

In every photo of the Miya twins, there was a mushroom-haired girl with glasses lurking in the distant background.

Once. Twice. Ten times.

How did she keep managing that?

Driven by a curiosity he couldn't quite explain, Suna began keeping an eye on this "background extra." He watched where she went, until one day, by chance, he saw her without her glasses.

Her eyes were big and bright, with lashes like butterfly wings. They were shaped like a cat's eyes, and one blink was enough to melt anyone's heart.

Suna lowered his phone and opened his usually narrowed eyes.

"Hey, wanna be my trade-for-trade model?"

Later, the Miya twins noticed that Suna, who used to sneak photos of them all the time, had suddenly stopped keeping their pictures on his phone.

In their place were photos of a short-haired girl who looked impossibly cute without her glasses.

And Fujii Aina would always remember that day: while her favorite pairing was having a heart-fluttering moment, the player she cared about least had set his sights on her.

"Suna, what does 'trade-for-trade model' mean?"

"It means I'll take your pictures for free."

"...And what do I do?"

"You let me take your pictures."

Later, she wrote that line into her fanfiction.

Only she changed the male lead to Miya Osamu and Miya Atsumu.
