A/N: Hi there! Welcome to my collection of one-shots for Katsuyu Week 2018. (Hashtagged as #KatsuyuWeek and #KatsuyuWeek2018 on Tumblr, but usually in lowercase.)

I'm just so glad and relieved that I could get this out on time. Granted, I knew we could submit stuff late, but I really wanted to try to be on time because knowing myself and my revision habits, this would've taken forever to get out. (I kid you not when I say this because I like revising until I'm content with what I've written.)

But, since these are all one-shots to celebrate Katsuyu Week, I figured that I should steer away from heavily revising them and just post most of them as-is (with minor revisions, of course).

This isn't a total AU, for the record. I decided to have it be set present time—kinda, sorta, but not really—before there's like a 10-year time jump, which then becomes an aged-up AU at that point. (I don't know how it ended up that way. I really don't. My writing just took form like that.)

I was planning on making all the one-shots be separate from each other, but for Day 1, it'll be a prequel to Day 4 because I really liked how things turned out with what I've written for Day 1 and wanted it to be wrapped up and a companion to Day 4.

For this one-shot, since the prompt is Bakugo, it's a bit Katsuki-centric, and everything's from his perspective, so fair warning: expect some coarse language.

With that said, enjoy!

Eventual

Day 1: Bakugo
(Prequel to Day 4: Tsuyu)

Katsuki wasn't sure when this had happened, really—when his eyes started shifting more to glance at Tsuyu in his classroom, that is. Whenever she entered the room or even made a subtle sound like a giggle, his eyes unconsciously darted toward her direction, recognizing her voice immediately.

He didn't mind it at first. Maybe it was because she had poked fun at him on that one day in the bus. He never got back at her for that comment. At most, he just yelled at her because then, the others started joining in, and immediately, he wanted to just kill all of them.

So, he told himself that whenever his gaze shifted toward her direction, unconsciously or consciously, it was because he hated her—because she never should've made that comment about how he'd never be popular.

Hah! One day, he'll show her that she was fucking wrong and that he'll be as popular as ever! All that fame and glory he'd get would be after he became a superhero and beat all those supervillains' asses one by one because he was the one who beat them—because he was aiming to be the best superhero—because she was fucking wrong, and he'll smirk in her face once she'll see how popular he became and tell her, "Looks like you were wrong, Froggy."

But lately, he noticed she was getting closer with that Fumikage Tokoyami. She started smiling and giggling when he was around—hell, he could've sworn he saw a slight blush on her cheeks the other day when he overheard Ochaco tease Tsuyu about Tsuyu's closeness with Fumikage.

Katsuki didn't like it.

He didn't know why, but he just didn't like any of it. Not one bit.

Katsuki was 26 now—a 26-year-old superhero who had just finished his share of patrolling around the city. His hands were itching to just punch something, but no damn villains had appeared even once today.

He had seen Tsuyu recently—or rather, he saw her in a magazine for some superheroine summer swimsuit photoshoot to promote cleaning up beaches. He had recognized a few of the other girls who participated, like Momo and Ochaco. He vaguely remembered how popular those two were among the boys, even back in high school, so he wasn't surprised to see them.

He was surprised to see Tsuyu in it, though. She had stayed far away from cameras for so long—hell, the last time he saw her was on their graduation day—that seeing her participate in a photoshoot, even if it was for cleaning up beaches, just seemed so unlike her.

When he overheard some stupid men behind him in the convenience store talk on and on about how hot and sexy Froppy was and how she should participate in more photoshoots, he wanted to punch the living daylights out of them.

And that same irritation occasionally bubbled inside him the more he thought about how popular she must've become now—because most likely, she had already forgotten about mocking his so-called popularity.

"Fucking shit," Katsuki grumbled, now realizing that he had unconsciously arrived at the beach and was standing on the sand—and he was still in his superhero costume.

He was about to turn around and head back until he saw a head pop out from the sea—and that same head looked at him in bewilderment upon seeing him.

His eye twitched. "Speak of the fucking devil…"

"Bakugo?" Tsuyu called out, still in her Froppy superheroine costume.

He could leave. He was half-debating on leaving, but there was something that seemed different about her that he kept staring at her as she swam toward him. It wasn't until that she finally got out of the water and stood about a few meters away from him that he realized what was different.

"You cut your hair," Katsuki said, his eyes lingering on how her hair was just a straight bob. "What, did you go through a break-up or something?"

Tsuyu raised an eyebrow at him. "Says the boy who recently got criticized for almost bludgeoning a small-time robber to death."

Katsuki glared and stomped toward her until he was in front of her. "'Boy?' I'm fucking 26! Do I look like a boy to you?!"

"Oh, really?" Tsuyu replied, raising her eyebrow further at him. "Sounds like you're the same old Bakugo I remember from back in high school."

Katsuki growled.

"And for the record, no, my hair wasn't cut short because of a break-up. I chopped it off while I was in a do-or-die situation while at sea. I went to a hair salon the other day to get it fixed up."

Katsuki narrowed his eyes at her, remembering that the other reason why he convinced himself that he hated her back then was because of her stupid smartass comments.

He realized then how her superheroine costume still clung to every curve she had in her body, and when he recalled how she wore that white bikini and posed—especially the solo ones where she was smiling innocently or her entire body was shown, showing off every damn curve she had—he immediately averted his gaze elsewhere, just anywhere away from her damn face and body because for fuck's sake, he was on the verge of having weird thoughts and feelings about her again like back in high school, except a hell of a lot worse.

He felt his breathing hitch once he realized their proximity. He hadn't realized how close he was to her until now because she had riled him up so much.

"Did you just finish your patrolling?" Tsuyu asked.

Katsuki grunted, his gaze shifting back to her, but it took everything in him to force his gaze to remain on her face and not on the various trickling droplets of water that slowly went down from her neck to the rest of her body.

"I see. I just finished up myself. I'll see you later, then?"

Katsuki blinked in surprise. "Huh?"

Tsuyu blinked as well, but nonchalantly. "I said that I'll see you later. Unless you want to talk about something else?"

Katsuki frowned, pausing in his thoughts momentarily to forget about the way her big eyes looked at him. "No."

"Okay, then."

Katsuki's eyes lingered on her figure as she walked away, doing his best to try not to look any lower, so he looked to the back of her head and noticed then that there were remnants of algae clinging to her hair.

"Hey!" Katsuki called out.

Tsuyu turned around, raising an eyebrow. "Yes?"

"You have algae on your hair, Froggy."

"It's Froppy," Tsuyu corrected as she started trying to fish the algae out of her hair. Tsuyu turned back around, letting Katsuki see the back of her head. "Is it gone now?"

"No," Katsuki replied, frowning.

Tsuyu began fishing all the algae out again, but she still managed to miss a few of them.

At that point, Katsuki started growling in frustration and irritation. "Oh, for fuck's sake, let me do it."

"Huh?"

Katsuki didn't even hesitate to stomp forward and start removing the algae out of Tsuyu's hair. It wasn't hard, considering how short her hair was now, but once he realized what he was doing, he unconsciously felt his hands linger a bit longer than he should've on her hair as he slowly removed the algae, piece by piece. He inaudibly gulped, realizing how soft her hair felt and the scent of the sea coming from her hair and entire body from their proximity.

When he finally removed the last piece of algae, he grunted. "There. Done."

Tsuyu turned around and stared at Katsuki in response.

Katsuki glared at her. "What?"

"You know, you're not a bad guy, after all."

"The hell is that supposed to mean?!"

Tsuyu smiled. "That you're not so bad."

Katsuki continued to glare at her, his gaze lingering at her smile, before he grunted.

"Well, thanks for your help. See you later for real now."

Katsuki didn't respond. He was tempted to just grunt again and then leave, but there was something pulling him—telling him—to stay and say something to her. After all, it had been about a decade now, and he wanted to fucking show her that he can be popular, but his mind felt like a weird jumble of thoughts, and everything felt so scrambled that he didn't even notice she was turning to walk away.

Within seconds, he unconsciously reached out for her arm and grabbed it.

Tsuyu blinked in surprise, turning back.

Katsuki stood rigid because why did he do that? Holy fuck, why in the world did he do that? And yet, that didn't stop him from hearing his heart beat so loudly in his ears, his lips suddenly feeling dry, and his breathing beginning to hitch.

"Bakugo?" Tsuyu asked, not moving a muscle.

Katsuki let out a soft exhale, inwardly telling himself and his heart to calm the fuck down and frowning before he cleared his throat. "You're not so bad yourself."

Tsuyu blinked in surprise again.

"And your hair—it's not that bad," Katsuki grumbled, just loudly enough for Tsuyu to hear. "'Cause, you know, you're not bad."

A few seconds of silence ensued, and as every second passed, Katsuki wondered if he should let go of her arm already, especially with Tsuyu just staring at him in response.

Finally, Tsuyu smiled. "Thanks, Bakugo."

Katsuki's eyes widened. There was just something about the way the evening sun shone down on them—on her face, specifically—that he couldn't help but be stunned. He didn't even realize that he had unconsciously let go of her arm until she gave a small wave with her other hand and started walking away from him.

Although that itching sensation he had to go punch something had disappeared for God knew how long now, he just wished he could make his heartbeat stop pounding so loudly in his ears—because he'd be damned to ever let her know how he was feeling, even if he didn't understand it himself.
