"Put some swim trunks on."

That was the text he had received about an hour ago from Eri. There were several hearts next to it, a sun wearing sunglasses, and a beach towel. It was the dead of winter and there was a winter storm littering the ground with snow. So, he sat in his room, a small heater under his desk as he was bundled up in his winter jacket while wearing his school swim trucks waiting for Eri to responded back.

Chances are this was from the eighteen-year-old Eri that had a habit of forgetting what season she was in. Or what time period she was in. He was now one hundred percent certain that at some point she loses her mind and then find it again before she's twenty. And that she refused to say what happens just that she was happy he was there for her.

It could also be the sixteen-year-old Eri that was who he was technically actually dating pulling a prank on him or something like that. Who knows there could even be some sort of dire threat that was going to require him to be wearing swim trunks. Like, uh, a villain with a water slide quirk.

Or maybe not.

Regardless, he was sitting in his swim trunks waiting for Eri to show up into his dorm room and do something with him.

"Holy shit balls its cold!" A Mature feminine voice said from behind him, the scent of Ozone now wafting over him and making his spine tingle at what that meant. "Wait it's snowing?"

He turned in his chair to see Eri. but one that was more Mature, her long silver hair cascaded all the way down to her butt, that same streak of red was now down to her chin, and a dazzling ring was on her finger. But, it was her outfit or rather near lack of an outfit that was drawing his attention away from just about everything and making his teenage heart go Plus Ultra.

It was a bathing suit, a red bikini that hugged her curves and showed off pretty much everything from her shoulders to her slender waist, though her long legs were half obscured by a see through piece of white cloth that was tied around her waist. She bounced over to his window, quickly pulling at the blinds to look at the falling snow.

"Oh man! We should have gone skiing. Wait, I can't ski." She turned to him smiling at him. "And neither can you, oh, you're already in your trunks. You won't be needing that jacket though where we're going!"

She grabbed him by the arm, smiling down at him with a radiant smile and spun him around. It was almost enough to make his head stop spinning. "How old are you, and its winter where are we going?"

"Oh, I'm twenty-sixish. And don't worry, about there where, it's about the when." She grabbed his hand wrapping it around her waist. With a wink, she flicked his nose and laughed to herself. "I forgot how cute you were at this age, oh well, now hold on tight, and try not to touch the time stream!"

"Wha-" The word was started and then stretched, coming out of his mouth like he was gargling. His room was there, then it wasn't. The sky was bathed in night and day with the sun swimming in a sea of stars while the moon spun around like a bird trapped in a room. It all blurred around him, and then came to sudden snap. "-at?"

"Don't worry, that feeling like you're going to puke will pass after you puke. The dizziness might stick around for a bit though, are you dizzy?" Eri released him, hopping back onto the warm white sand that he was currently standing in. The ocean spread out behind her and the warm rays of summer washed way, the chill from his room that still lingered.

A firm hand slapped him on the back. "Don't worry, I remember hating my first time being rough, you get used to it pretty quick, but Eri enjoys it if you act sick a bit."

"I do not!" Eri pouted, both hands balled into her fists at her sides. She spun on her heel kicking up the sand and crossing her arms. "You're just cute when you're sick!"

"And you're sadistic when I'm sick!" The voice said again, and a man stepped beside him, he was tall, wearing large board trunks that went to his knees and was shirtless. He was muscular, very muscular. But it was the scars on his hand that told him everything he needed to know. That and the ring that matched Eri's. "If I didn't know any better I'd think that you used your quirk to make me sick for longer."

Eri didn't say anything, instead, turning to face away from them while still pouting, hands now on her hips. "I don't know what you're talking about."

"Eri." The older version of him, warned taking a step forward, a lot of things changed with how he looked, height and overall muscle mass were the biggest one, but there was no hiding his messy green hair even if part of it was shaved into an undercut. He leaped towards the older Eri, grabbing her by the hips waist and spinning her around.

She squealed slapping at his arms and laughing. "What! I didn't! I promise!"

He stood, shaking off the dizziness and pushing down the need to puke. The warm sun and the cool sea breeze helped a lot, but then there was the confusion and a whole slew of questions that needed to be answered. "Umm," He drew both of their attention. "What's going on?"

"Oh," they both said.

"Did she not explain that?" His older self said standing upright, Eri still flailing as he held her over his shoulders like a sack of potatoes. "Uhh, I'm not really good at explaining this future stuff, well but that's okay, I'm still confused about it too. The trick is to not worry about it."

"Hey!" Eri screamed kicking her legs. "Put me down! I'm supposed to explain!"

"Basically," He said ignoring Eri, and smiling wider. "It's like ten years in the future, we're celebrating Eri's birthday, and that includes the Eri that belongs in this time so, uh yea! You're actually her birthday surprise!"

"This is no way to treat your wife on her birthday Izuku!" Eri stopped flailing and crossed her arms into a pout. "Seriously, if I wanted to spend time with you I could have just traveled back and spent the day doing something like cuddling and watching a movie, oh it was snowing could have built a snowman or go skiing. Which by the way you're taking me skiing for my birthday."

"What? Are you going to change your birthday again?"

"Yep!"

Oh, so this was what his relationship with Eri was going to turn into. It looked fun. And nice. And Eri was really hot when she got older. "Wait, won't me being here change the timeline or something?"

"Don't worry about it," Eri laughed swatting her hand at him and laughing, "I'll put you back where I found you. But, now then, let's go find me and give you to me, so me and you can go do stuff without me being jealous."

His older self sighed, looking at her then back at him. "For the record yes, she does enjoy saying things in the weirdest way possible just to confuse people, and herself."

"Yea, I think I got that," He looked up and around trying to find out exactly where he was besides a beach, there was a nice looking house behind them but that was about it. "But, how am I here? And how are there two Eri's? I thought that couldn't happen?"

"I so don't want to explain stuff on my birthday!" Eri half groaned, slapping on his older self's arm and pointing to the ground. She was placed down gently. Then squeaked, her face turning red as one hand went back to her butt. She glared up at her husband.

He smiled at her. "Sorry, couldn't help myself."

"Anyways, there's basically always been two Eri's in your time, like one older me and then the kid me. This is no different, we're just when that kid Eri is Sixteen because this is when you're twenty-six, so yea. I tried really hard to make that one make sense!" Her face was still red as she swatted him in the chest. "Just for that, I'm going to-"

"Fuck!" she swore both fists at her sides as she turned stomping off towards the house, "Just made a timeline where you and Itsuka are a couple! This is why I'm so done meddling with the timeline, one little incident, and migraine for days."

His older-self just shrugged at him. "Look, you'll get used to it, well kind of, but she's worth it, trust me on that." He already had a feeling. "Anyways, I'm going to tend to my wife, if you head up the beach ways you should be able to find Eri walking along the beach."

His older self half sprinted after Eri, before turning backwards his speed not decreasing. "Oh, Uhh, there's not a lot of advice I can give you that'll help, but just believe in yourself the way All Might believes in us and you'll do great!"

Easier said than done. He watched his older-self scoop the Eri up and dive into the house, the curtains closing behind them. That was probably a good clue that they wanted privacy.

Feeling the sand under his feet and the cool breeze blowing against his hair, he had almost forgotten the snow storm that he was in this morning. Also, he was probably going to get sunburnt, like really burnt.

The beach was beautiful, with sparkling blue waters and shallows that extended for what seemed like miles out to see, the waves were small and gentle things. This was a place to relax, a place where time seemed to stop. In a way, it made sense for Eri to bring him here. Or for him to bring her here.

A few people, mostly couples, crossed paths with him, most just nodded in return a few were lost in their own worlds, but all of them were smiling. He reached a bend, where stones stuck out from the shore creating small tide pools, and there he saw her.

It was Eri, his Eri, the one that he had asked out, the one that he had dated, the one that he had started all of this with. Even if they were the same person, just different points in her life, this one was his. She was - as always - beautiful, with her hair tied up by a band of yellow flowers, that single strand of red shinning like the north star to draw him in.

She was wearing a black bikini that only served to remind him of how much that red sweater of hers hid. She leaned down into the tide pools to observe something when her red eyes finally snapped to him.

"Izuku!" She half screamed half laugh, jumping over the tidepools to run towards him. He ran too, catching her as she jumped into his arms, and spinning about before they fell to the sand. "You're here!"

She snapped up, looking around. "You're here? How are you here? Why are you here? Am I here?"

He couldn't help but laugh, grabbing her sand covered hand and placing a kiss on her knuckle. "I'm here Eri, and happy birthday."

"I'm confused." She stared at him before shrugging. "But I'm mostly happy that you're, but how are you here?"

"Your older-self brought me here so that she and future me could have alone time while you get to have me as your birthday present." He pulled them both up off the ground, holding out his arm for her. "So, let's make the most of it."

She grabbed onto his arm pulling it into her - soft - chest and placing her head on his shoulders. "So if you're my birthday present, does that mean I get to do whatever I want with you?"

That made his lips dry. What did that mean? How was he supposed to answer that? What was she planning? "Um, well what do you want to do,"

"First, I want to go on a nice long walk, then, I want you to give me a Massage and feed me strawberries, then I want." She paused, her face flushing as she bit her lip. He wanted to kiss her. "Then, I want to watch the sunset with you, and after that, I want to sleep in the same bed as you."

"Are you sure?"

She nodded. "Yep, besides, its what we're going to be doing tonight even if we don't, and I really want to wake up cuddling you. Something about that just sounds so wonderful."

After a week-long vacation at Okinawa, his classmates were slightly perplexed how he got a tan in less than an hour.

AN: Can I call this the end?
