Summary: Hillary tells Kai that she'd been sleeping with Tyson during the 3rd World Championships – and he is not happy.


Kai gets the shock of a lifetime when Hillary tells him she slept with Tyson during the 3rd World Championships.

To say that he is horrified would be an understatement. In the midst of his end-of-a-work-day routine in his bedroom, he bombards Hillary with questions: when, why, for how long, and why Tyson fucking Granger.

"Couldn't you fuck Kenny instead? Or Hiro? Fuck, even Brooklyn would have worked."

Hilary leans against his dresser, watching Kai as he aggressively uncuffs his sleeves. She forgets the nervousness with which she initiated this conversation just enough to roll her eyes at him.

"I knew you'd turn this into an ego thing."

She seriously doesn't get it? Kai stares at her incredulously, before rephrasing his question.

"Why Tyson."

"I dunno. He was just there."

I should have fucking known, Kai thinks, stomping around the room, loosening his tie and throwing it in the laundry basket; his head a haze of red. Hillary and Tyson, he thinks, it's so fucking obvious. That man had an uncanny ability to leave a mark on everything Kai has ever loved - literally.

"What? He was good to me. Don't worry."

Kai is a lot of things in that moment, and 'worried' is the last of them. He takes a deep breath: not failing to note the way Hillary, despite her air of confidence, is sinking into the dresser.

Hillary continues against the silence, joking to dispel her nervousness.

"More than good, actually. We hated each other. Hate sex is the most amazing thing."

She looks into the distance and Kai scowls when he realizes that she's lost in memories of the time she was fucking Tyson Granger -

Words slip his mouth before Kai can stop himself, "We can have hate sex."

He thinks of what Hillary hates - beyblading? When Kai leaves potholes in the backyard from beyblading too hard? She absolutely abhors Tyson -

Fuck.

There's an amused expression on Hillary's face, and he thinks he could drown Tyson in the river that he can build from his feelings of dislike in that moment.

"You know, sex after his battles with you, Kai - it was absolutely earth-shattering -"

Kai wants to puke. "Enough."

He doesn't think he can hear more of this. The thought of Tyson bedding Hillary while Kai mopped around for losing makes him dizzy with rage.

Kai feels disgusted and Hillary doesn't look entirely comfortable herself. Despite her snarky comments, her knuckles are ash-white against the black dresser.

His voice is a desperate plea, and he questions without a question. "Why are you telling me this now."

He bites the inside of his cheek in something he's all-too familiar with when it comes to Tyson: insecurities. Is she going to leave him? Will it be for Tyson? What does she want out of this?

And Hillary's response feels like a volcanic fire was lit and then burnt out inside of him.

"Because Tyson was asking if we could...you know, hookup again. He broke up with Julia and I'm single too."

Fuck no!

His tone is threatening with how much cold rage it carries.

"You are not single, Hilary Tatibana."

"Technically, Kai, I am. No one knows about us."

"Then fucking tell him."

Kai scowls at her, only to have her raise her voice an octave higher than his.

"You know I can't do that!"

Kai knows what this is about. It's the we-need-to-let-the-world-know-about-us conversation again.

Keeping their relationship a secret was his idea and she'd agreed - but only reluctantly. I don't understand why, she'd said. I'm not dealing with everyone's bullshit, he'd said. It will die down in two seconds, she had insisted. Two seconds wasted dealing with everyone's bullshit, he'd retorted.

Kai had a simple policy: don't fix what's not broken. And Hils and him were doing fantastically fine. He did not want to deal with more drama until it was necessary.

Of course, he regrets it now. This is what happens when you're famous and don't hold an urgent press conference to announce your personal life to the entire fucking world - everyone starts to think your partner is an open game.

"If you're gonna keep scowling like that, Kai, then I'm going to have to say yes to Tyson. At least he isn't this moody."

The volcano in him erupts again at her final comment. "Fine!" He pockets his wallet and phone, and reaches for the car keys, "Go have earth-shattering sex with Tyson, then. I'm fucking leaving."

"Okay, Mr. Drama Queen, yeesh." Hillary knows better than to engage with his comments, and only raises her voice after him. "Get some detergent on the way back, you're almost out!"

Hillary doesn't want to be dismissive of his millions-worth of complicated feelings regarding Tyson - but she's also way too stubborn to let him have his way about this for so long. She thinks ten fucking months is enough to start telling people - and she is too much of a socialite to keep up with this charade any longer.

She knows Kai will come talk to her when he is ready. And until then she can, at the very least, get some joy out of his sourpuss personality.


When Tyson asks Hillary to meet him at the food court at the local mall, she has an inkling there'd be some yelling, stomping, and cursing - and there is. Tyson drops his bag on the chair across her, drags the chair, and points an accusing finger at her - everything just as she expected; except for his words.

"How long have you and Kai been together?"

Hillary spits her coffee, feeling the blood pumping behind her ears.

"What? Who the fuck told you?"

Tyson rolls his eyes, "You just did."

Tyson isn't stupid. Kai Hiwatari was bloody scowling at him all day at work for no reason - that too, only 24 hours after Tyson had asked Hillary to hook up with him. Yeah. He'd put two and two together alright.

Kai was anything if not readable, especially to Tyson. And judging by the brunette's reaction, they hadn't wanted anyone to find out.

"Nice going Hils." Tyson says sarcastically, crossing his arms, "You triggered his insecurities. And mine - man looked like he wanted to beat me to pulp."

Tyson frowns when Hilary's lips cracked into a small smile at the display of antagonism between the two beybladers, something that has always been a bit comical to her - when it wasn't downright annoying that is. Her momentary anxiety is now replaced by playfulness.

"Ten months." Says Hillary, and at Tyson's questioning eyebrow, she adds, "We've been together for ten months."

"You didn't have to tell him what I had said, dude!" Tyson reiterated after Hilary smiled at him mischeviously from behind her mug, "I don't want to be dragged into Kai's sex life. This isn't even about me!"

"Oh, please, Tyson. Everything that Kai does is about you."

Tyson recognizes the look on her face - she is up to something. And he hates it.

"You're both crazy."

Hillary ignores him, "It saved me the trouble of telling you no about your offer."

"Yeah, sure. Send your lapdog to do it for you."

Tyson is just about to snap when Hilary passes him a knowing smile and points a singular finger around her; gesturing towards the fact that they're in public and Tyson doesn't need bad press so soon into his new job at the BBA. Begrudgingly, Tyson decides to pack up and leave before things get too heated between them in the middle of an overcrowded mall.

"Hey!" Hillary says teasingly behind him as he leaves, "I happen to like my lapdog. He's very cute!"


Hilary knows what Kai's rather aggressive, out-of-the-blue makeout session is about. And while she's not the one to complain about getting laid, she does have a problem with the mumbled words that are escaping Kai's lips in between the heated kisses.

It's the 'How long were you with Tyson for?' that finally earns Kai a shove from her.

"Get off me."

She squirms under him, trying to get out of his arms, with the sheets wrapped tightly around her. She tries to glare at him when he playfully blocks her path, but it's hard for her to look him in the eye right now given that they were halfway into a passionate foreplay only a few seconds ago.

She sighs instead, "Jealousy is not a good look on you, Kai."

"I'm not jealous." He's quick to retort, and she rolls her eyes. She'd caught the mumblings earlier, the 'fucking Tyson's and the 'everything I have loved's and the 'of all the people on the planet'.

When Kai sees her leaning away from him, the roll of her eyes, and her disengagement towards his insistent questions, he decides to be honest. So, in the middle of his bedroom with his shirt on the floor and hers on the dresser, he looks up at the ceiling and asks.

"Was he better than me?"

Somehow it comes out more vulnerable than Kai had intended. And Hillary sees it. Her eyes soften, and he relaxes under her reassuring palm against his cheek. Her other hand finds its way to rub one of the arms caging her.

For a moment, this gesture is enough reassurance and she knows it. So it doesn't bother him to see her smiling teasingly at him when he glances down at her.

"Tyson has more trophies on him than you do. Arguably, he was better."

He gently taps away her hands all over him, mildly annoyed.

"I obviously didn't mean beyblading. But thanks for the reminder."

It's Hilary's turn to block his path, and she does so by wrapping her arms around his neck and pulling him in a reassuring embrace. "I didn't say he was better."

Kai mumbles the words earth-shattering sex and Hillary only rolls her eyes, "Kai, it was just sex. I wasn't in love with him."

"How long?"

"I don't know. A couple of months. Maybe six. Then Tyson got a girlfriend and I fell in love with someone else."

"Your stupid ex." Kai scoffs into her bare shoulder, still in her embrace, and still not looking at her.

"No, Kai, you."

Hillary's feelings for him were never a secret - she had been in love with him for years and the fact was obvious to anyone with half a brain. She had also expressed those feelings multiple times, and with so much depth in her eyes that he feared that if he looked at her, he'd sink and drown in the intensity of the emotions she carried for him.

So it's easy for him to believe her now. Her message is clear: it doesn't matter what happened with Tyson, it doesn't matter how good or bad it was, it's in the past. She's with Kai now, and she's in love with him - nothing more, less or in between.

He doesn't doubt her affection for him - he is just super annoyed by the fact that Tyson fucking Granger was ever a contender for what was his. He feels possessive of her, and everything she's given to him. Mix that in with the dark of his insecurities around Tyson and it's not a pretty color.

He sighs, realizing he's let his childish stubbornness get the best of him again.

"Sorry." He mumbles just as gently as he'd mumbled his snide remarks, "Tyson brings out the worst in me."

She only teasingly adds, "Yeah, the whole world has seen that."

The slightest edge in her voice makes him glance down and he finds a glimmer of hurt underneath Hillary's reassuring front. He searches his brain for their conversations together, and it doesn't take long before it clicks.

"This secrecy thing is exhausting you." He notes out loud.

He knows she has her own insecurities about this relationship too. He doesn't blame her for her comments over the past few days. The sneaking out, the lying to people she loves, the girls that hit on him and the guys that hit on her; she's the last person on the planet who would be inauthentic but she's doing it for him.

But she's reaching her breaking point and the realization hits him like a sandstorm.

Over the past few months, he's become familiar with her quirks enough to know when she needs assurance and how to give it. So, he gently gets off her to wrap his arms around her instead.

"I'm ready to tell people if you are."

The answer comes as easy as free falling to him; his tone firm, and decision unwavering. He had long since decided that Hilary's comfort mattered more than his own; and she was very obviously distressed right now.

He gets his answer in the way she relaxes against him, in her small sigh against his shoulder, and in the relieved, "Okay."

The moment doesn't last long, because she's back to her teasing self again - another quirk of hers that she only displays to avoid being too vulnerable.

"So, where's my trophy for sleeping with the three-time beyblade champion and the runner up?"

He smirks before roughly lifting her giggling form off the mattress and placing his mouth against hers.


AN:

Hello hello hello.

This has been in my drafts for ages and I just had to brush it up and post it.

It started off as a comical conversation in my head and then, bcz I'm a slut for exploring kaihil at different stages of a relationship, it evolved into a how-long-before-they-go-public and what's-their-first-lovers-spat-going-to-be-like thingy. And here we are.
