"You know," Oikawa let out a light laugh, "I've played so many games where the pressure was unbearable, but this is the most stressful moment of my life."

Silently, apprehensively, you waited for him to continue.

"I've been trying to gather up the courage to tell you this for a while, but I like you. A lot. More than a friend. You're amazing, smart, and kind... And I think- no, I know, that I'm in love with you." His brown eyes softened as he looked at you.

You cringed, "Oh, Tooru... that's really nice of you to say, but..."

"But?"

"I'm sorry, I don't feel the same way," you admitted, "It's not you, it's just that I'm aromantic. I'm not interested in anyone that way."

Oikawa kept quiet, the light fading from his eyes. An "oh" floated out of his mouth.

"I still want to be friends with you," you said, desperately hoping he would understand, "We can still practice volleyball and watch alien documentaries."

He remained silent for a few minutes, before he smiled and said, "Of course! I would never want to stop being friends with you!"

There was a strange light in his eyes as he gazed at you, but you took it with a grain of salt. It was just that he was feeling hurt, right?

Iwaizumi poked his head around the corner, "There you both are." He gave Oikawa a suspicious look, but Oikawa waved cheerfully, as though nothing had happened.

"Everything alright?" Iwaizumi asked, looking from Oikawa's too-broad smile to your awkward expression.

"Peachy," Oikawa said carelessly.

"Well, coach is already in the gym. He'll kill you if you make us wait on you."

"I'll be right there."

Iwaizumi turned around with a second glance and disappeared around the corner. As soon as he was gone, you turned to your other friend. "Are you sure you're okay?"

"Absolutely," Oikawa replied, patting you on the head. But as you walked to your own club, you didn't see the way his intense eyes lingered on you until you were out of sight.

There was something else blooming in the hollow space where hope had just died. Something that wasn't ready to let go.

—---------------------------------------

Physical Education had just finished up and your throat was dry as a desert. You picked up your water bottle and took a swig, only to find that it was empty. You let out an annoyed noise and walked over to the water fountain, unscrewing the lid off your water bottle and filling it up.

You turned around to leave when a guy, tall and slightly dorky-looking, stepped into your path.

"Hey, um," he rubbed the back of his neck nervously, "I know this is sudden, but I was wondering if you wanted to get a coffee together? Just the two of us?"

You blinked in surprise, then shook your head, "Sorry, but I am-"

"Taken."

Hands came down on either shoulder as Oikawa pulled you close. Shocked, you looked up to see him smiling at the other boy, "She has a boyfriend. Sorry, buddy." He didn't sound sorry at all.

"Tooru-"

The other boy blushed, "Sorry, I didn't know! Honest!" And he hurried off without looking back.

"Tooru!" you snapped, turning around, "What the hell was that?"

"What?" Oikawa asked innocently, "I saved you from an uncomfortable situation!"

"I had it under control," you retorted.

Oikawa shook his head, an infuriating smile on his face, "Not everyone is going to understand your whole 'I can't fall in love' thing," he imitated you in a very unflattering way, "Hell, I don't think they'll even believe you and think you're bullshitting. But I understand and I think pretending to date me would be easier to explain than your aromanticism."

Doubt crept in. Maybe he was right. You'd gotten lots of confessions and they always gave you a weird look when you explained you were aromantic. One had even said "I can change that."

"Fine, but only when we're around other people."

Oikawa smiled, "Pinky promise."

You rolled your eyes at his childish behavior and linked pinky fingers. It felt strangely final, as though you were signing away something more important than fake dating.

"Did everyone see her spike during PE?" Oikawa suddenly yelled out to a group of classmates, "So strong- that's my girl!"

"What the fuck are you doing?" you growled under your breath.

Oikawa merely grinned at you, "Getting the word spread."

He wasn't wrong- by the end of the day, everyone in school knew that you, but more importantly Oikawa, was taken. You got a lot of glares from girls, but Oikawa continued to sell the image, linking arms with you and dragging you down hallways where you'd be seen by the most people.

"When were you going to tell me?" Iwaizumi huffed.

"It's just fake," you said simply, "He's just helping me avoid confessions."

"Huh," Iwaizumi said, staring hard at Oikawa. For a moment, he looked at you and parted his lips, like he was going to tell you something, then shrugged and moved on. A sudden sense of foreboding flooded you.

—--------------------------------------------------------------

As days went on, Oikawa pushed his hand farther and farther.

Holding hands turned into pecks on the cheek, turned to kisses on the lips, turned to attempted make out sessions. He'd innocently whine, saying you had to "keep it realistic".

"We've been 'dating' for six months," he told you matter-of-factly while putting a diamond necklace around your neck, "It's only natural that I'd give you a present for our anniversary.

"No more kissing," you said, putting a hand up to stop his lips from crashing into yours.

"But we've been dating so long, it would be weird if we didn't kiss," Oikawa complained.

Your heart pounded, not in a romantic way, but in a stressed, suffocating way. You stepped back, necklace cold against your collarbone. "Tooru, I mean in. No more kissing."

"But-"

"No!" You tried to be firmer this time, "This was supposed to be for appearances."

Oikawa's expression darkened, "So I'm just a prop in your little identity game?"

"That's not fair! You were the one who came up with this idea!"

"Because I care about you," he snapped, "And I thought if we spent enough time together, you'd realize you care about me too. Not like a perfect romance novel but something close enough."

You choked up, "You're trying to change me."

"No, I'm showing you that you're wrong about yourself."

The words hit like bullets, "So you think I don't know who I am?"

"I think you don't know who you should be," Oikawa snarled suddenly, rage contorting his face, "Now shut up and be grateful."
