I Dare You // Larry AU

Prologue.

A/N: This is entirely a work of fiction. Anything that happens is not real. Also L and H are both only children.

"What do you mean you're getting married?!" Louis yells.

"Louis... I've explained this." His mother says patiently.

"You're telling me you're marrying someone you met six months ago?! I haven't even met her son!" 

"Louis... It's love. Alright? I thought you'd be more accepting about this... You love Anne."

"Yeah, I do like her... But- I don't know. I'm just- shocked." Louis says. 

It isn't that his mothers marrying a woman. He's known she was Bi since he popped out of her. It's just how early the marriage is happening. He's only met Anne a handful of times, and he only found out about them about two months ago. Hell, he hasn't even met her son, and now they're gonna be step-brothers?

It's just a lot.

***

The wedding is two months later, and he's still yet to meet this future step-brother. Apparently the bloke was too busy to take a bus to come say hello.

He's going to be moving in with them, though. After the wedding. He and Louis are going to be living together on their own when their mothers are on honeymoon. And Louis hasn't even met him.

The weddings about to start and Louis' just skulking around, trying not to die of boredom. 

Then the one person he hates most walks in.

Harry fucking Styles.

Immediately, he storms over. "What the fuck are you doing here?"

"Could ask you the same thing, Lewis." Harry drawls. They're dressed similarly. It's unnerving.

"It's my mothers wedding, dumbass." Louis spits.

Harry's eyes widen. "No- Jay's your mother?!"

"Oh for fucks sake." Louis groans. "Seriously?"

Harry scowls. "Of all the fucking guys, I had to get you as a step-brother."

"I'm not happy about it either, wanker. At least I was willing to make an effort to meet you." Louis huffs. 

"I was busy."

Louis snorts. "Of course you were. You're so important, forgot about that." 

Harry grabs him by the collar, shoving him against a pillar.

"Harry! What on earth are you doing?" Anne, Harry's mother exclaims. Louis can't hold back the smirk.

"Uh..." Harry says. What a way with words he has. "He's a wanker?"

Anne glares. "Let go of him." Harry does, stepping back. "Since when do you two know each other?"

"Um... You know the wanker I fucking despise?" Harry asks. "That's him."

"Oh for petes sake." Anne says. "Well, I don't care if you hate him. You're step-brothers now and you're going to get along whether you like it or not. This feud between the two of you is childish, and I'm putting an end to it now. I don't want to see you two fighting at all or so help me god." 

Then, she walks away. Harry sighs. 

"I can't wait to beat the shit out of you when they go on honeymoon." Louis growls.

"Ditto." Harry says, then he flounces away.

***

The wedding is torture, well. No.

It's a lovely wedding. His mother looks beautiful, and the service is beautiful. Maybe he cries.

What's torture is having to sit next to Harry Styles and not punch the shit out of the stupid git.

During the reception, Harry's mother makes them spend time together. They have to sit next to each other during the dinner, and Harry spends the entire time talking to him about stupid boring shit.

He doesn't see much of his mother, unfortunately, since she's so busy. He did get to hug her, congratulate her. Tell her how amazing she looks.

He finally manages to get away from Harry, and then gets to avoid him the rest of the night.

***

"Come on, Louis." His mother says.

"Do I really have to live with him?" He whines.

She tuts. "It's only two weeks, Louis."

He hugs her. "But I fucking hate the fucker."

"Well, try to get along with him, yeah?" His mother says. "Please?"

"I'll be civil." Louis mutters. 

"Thanks, boobear." His mum says, and there's a snigger behind him.

He turns, and Harry's standing there with a stupid smirk on his face.

"Try not to kill him, yeah?" His mum says anxiously.

"No promises."
