A/N: Just a quick note: _person_ (body) - is the format of the pronouns. Person will be mentioned first, and appropriate gender pronoun of the body is put in brackets; to avoid confusion.

… How does one explain how we reached this point? Mission was over. Police and heroes were gathered outside the ruined building. Aftermath of short skirmish was still there. Two students on their internships were with their respective mentors. Villains have been captured and their relatively big gang met the light of justice. It was just big enough for Sir Nighteye to request cooperation with Ryukyu Tatsuma. And although the operation went rather smoothly, one small unprecedented error occurred.

Skipping over all unnecessary details, we arrive at the current situation: Nighteye couldn't help but sigh, Ryukyu is in utter shock and Lemilion and Nejire-chan were… well, take a guess. Absolutely dumbfounded, only begins to describe it.

"This… this is clearly my pupil's fault. My apologies, Sir." Ryukyu was the first one to collect herself and speak. They had to address this issue.

"No, this is clearly an error caused by my student." Nighteye adjusted his glasses. "Normally, I'd have given you an earful about your unenergetic report, but in this case, I guess have to make an exception." He was addressing the two UA students. "How this happened, I don't know. I don't have to know, and I don't want to know. I have warned you, everyone, about that villain's ability and yet…"

"Mm, we screwed up. Big time." Mirio was the first one to admit fault, except that the words came out from Nejire's body. He didn't sound stressed, but it would be a lie if he said he wasn't uncomfortable.

"And this time, you will have to reflect on your actions on your own. I don't like repeating myself." Sir Nighteye had to be strict with him this time.

"Same goes to you too, Nejire." Ryukyu was disciplining her own student. "This wouldn't have happened if… no, nevermind. I'll have my fill of disciplining you later. Now, you two need to make sure no one outside of us 4 knows that you two swapped bodies. We will explain the situation to your teacher and principal of course, but you two must not tell a soul."

"Not even to Ta-?"

"No." Nighteye cut him off before he could finish

"When is this going to end?" Nejire spoke this time, the voice sounded dreadful, even more so when you know it was Mirio's body that was speaking. Needless to say, she was super uncomfortable.

"According to the user, the effect persists for 24 hours at longest. It can end sooner, but by how much, we don't know." Ryukyu explained.

"And because I used my Foresight today, you can't count on that either."

"In conclusion, you two must make sure no one finds out about this. Try your best to impersonate each other."

M(N): "Wait, does that mean we also have to switch rooms as well?"

"I trust you are both mature enough for it not to pose a problem. "

"B-but… our clothes… How do I change them without…", Nejire (in Mirio's body) couldn't finish what she was saying. And this was indeed, a problem. Unpleasant for both sides (take a guess who was more uncomfortable). Everyone understood in an instant.

"W-we'll think of something. It can't be too hard." Mirio tried to assure her.

But Nejire didn't listen. She (he) attempted to tuck his (her) shirt, but it turned into a pinch since they're both wearing bodysuits.

"Ouch-"

"And… and Togata", she finally composed herself, "you'll respect the boundaries, right? Can I count on you?"

"Of course! I promise I'll just head straight to sleep when we get back!"

If anything, there was at least one thing they had luck with. Tomorrow was Sunday, so they could just wait in their rooms for the effect to pass.

"Argh, these muscles feel gross. How do you put up with them?" Nejire added as she was rubbing her (his) biceps. She felt like a meatball and she didn't like it. She was a meatball now.

"Hado-… I'm proud of my guns; please don't diss them like that."

They changed their clothes, not by themselves - but by the help of the third party.

In Mirio's case, he was blindfolded and changed by the girls of Ryukyu's agency.

"If you so much as move funny, or try to peek, we'll be gauging your eyes out later."

"Ok, ok. Don't worry."

Like, sheesh, women. Chill out, it's Mirio we're talking about here. Just because he's tempted a bit doesn't mean he'd actually do it.

Nejire, however, didn't have to be told. She was changing by herself. Too afraid to change the underwear. She was done in less than 30 seconds, godspeed.

Later that day, they were on their way to the dorms and met Tamaki in the school grounds.

"You guys are late. Tough mission I assume?"

"Oh, if you only knew…" Nejire spoke.

"Did something happen, Mirio?"

"O-oh, nothing big, I just feel really uncomfortable." shivers

"Yeah. Me too. I'll just head straight to sleep now."

"Straight to sleep? But it's only 7 in the afternoon."

"I-I need my beauty sleep, you know!" Mirio trying to come up with excuse on the spot didn't go very well.

"HEY!? What the hell are you saying?" Nejire was in disbelief.

"But it's true, right?"

"You could have just said 'I'm tired from using my quirk' or something!" Big buff guy was stretching cheeks of short, blue fairy. Giggles and jiggles could heard in the background. Looks like rumors and misunderstandings are already starting to spread.

"Oh damn, you're right!" Realization hit him with a frying pan; he felt dumb.

"Did you guys… switch bodies?" Tamaki took a wild guess as a joke, but little did he know he was actually spot on.

SHOOK. He caught on way too quickly.

"PLEASE don't tell anyone! I beg you!" Nejire pleaded.

"Yeah! Me too, we were ordered to keep it a secret." Mirio joined in the plea.

"Oh,... you're serious?", (He' losing it)… "I'll just go to sleep now… see you tomorrow…"

And so he went. But it wasn't long before the 2 unlucky ones followed. Without so much of a word with their classmates, both of them headed straight into the rooms belonging to the body they are currently possessing .

In Nejire's room.

Ahh, 'Tis my first time in a girl's room. It smells nice…. Now, what do I do? First thing's first, I need to get ready for sleep.

Easier said than done. Getting ready for sleep meant going to excruciating trials of changing clothes and the infamous bra removal. How does one do all this whilst respecting the 'boundaries'?

A daunting task, to be sure, but it is at the dire times like these when a man must step forward and do the right thing. The right thing being, of course, maintaining the hygiene on this delicate body. And going to sleep with a bra on isn't the cleanest to do, therefore off with it. Yes, this is purely for hygiene.

Changing into pajamas wasn't too hard; he did with his eyes closed. But the accursed bra stood there menacingly like a Jojo villain.

It was no easy task, the bra's lockdown system was more complicated than Rubik's cube. That forced him to use a mirror, which inevitably led to exposure of her lean lower back. He didn't have to feel so dirty for seeing it, but he did.

"Ahh, damn. This is so embarrassing. I feel like I'm breaking my promise already."

Taking it off caused more back pain than he expected and took longer, way longer than it should have. 15 minutes to take off the damn thing.

Redder than a tomato, he let out a sigh of relief, letting the missing blood flow back into his (her) hands. But the true test of nerves has yet to takes place. Bra was never the last boss, he was merely a foreplay. Hors d'oeuvre before a main dish. Two main dishes, in fact.

Freedom. They are now unrestrained. Mirio never experienced something like this before. It was exhilarating and …. So. Hard… to take off his mind. It took all his willpower to keep hands in the pockets, and walk as slowly as he could to the bed.

Sleeping on stomach, as he usually would, was out of question now. Laying on his back, staring in the ceiling until 'excitement' drains the last bit of energy, is the only option he has. It was (only) 7:14pm. Let the torture begin.

In Mirio's room.

'Now that I think about it, this is my first time in his room, no? Heh, it's kinda nerdy~…' There were two posters on the wall; one dedicated to All Might, other to his favorite rock band. On his desk there were some notebooks, pen box and a single framed family photo. In it there was Mirio striking a pose: fist in the air and a red blanket as a cloak. He couldn't be older than 7. Behind him was his father giving peace signs.

'Aww, that's so cute…' she said as she took the picture in her hands. 'I wonder if he's got more of these?' So she reached to her (his) pocket and realized… that in the commotion, they didn't switch phones. So she ended up with his.

It didn't have password, and oh – boy, does she have a lot of options to choose from now…

Tomorrow morning.

Mirio woke up, in his own body. 'What a relief, we switched back in our sleep.' It's relatively early, 8:21 in the morning. He took his phone that he found next to the pillow and went outside as soon as he could. Even though there he committed no real breach of boundaries, he still feels guilty and wants to apologize.

Three of them agreed met between dorms of classes 3-A and 3-B.

"Ah, there you are Hado. Look, there's something I need to tell yo-…" – He began but as they were approaching he noticed Nejire crying and Tamaki looking severely uncomfortable next to her.

"WAAH…" she wailed. It was hysterical crying, childish but not angsty. And in this moment, Mirio's legs froze; felt as heavy as the lead. 'Oh my God. I unknowingly did something awful, didn't I? Removing bra was a mistake after all-! H-How do I atone for this? … ' As he continued to curse himself internally he heard her say something which threw him off guard.

"Even after I t-told you to respect the b-boundaries… I-… I did... that." She tried to peek at him through hands she was hiding her face in. But there's no way she could look him in the eye, no. Instead, she turned to Tamaki and, almost yelling at him, said: "You tell him!"

"How do I tell him something I don't know?" he asked being caught completely by surprise.

This was the ultimate uno-reverse card. This time, Mirio's mind froze, and then went into an overdrive. What could she be implying? Could she have done something indecent… Dirty? The very thought of it made his head spin.

But before he could dive deeper into this, she said: "J-just take your phone …. Then go to 'messages'…"

He followed her instructions like a zombie, and what he found blew his wildest expectations out of the water. His eyes glued to the screen, poker-face unwavering. The embarrassment he's feeling has no way of manifesting itself through facial expressions, body temperature, or skin color. It's off the charts.

Tamaki already felt his own second-hand embarrassment building up, tucking his sleeve. He didn't know what's gotten Mirio so pent up, so he was about to find out. Walking over to him, Tamaki decided to take a look. What he saw is going to scar him for life. If he was in Mirio's shoes, he'd die of heart failure, but the sweet release of death isn't coming his way today. Instead he has to live with the second hand embarrassment of what he just witnessed. It punched him in the gut so hard it knocked the daylights out of him.

On the phone screen, there were pictures – upon pictures – of Mirio's childhood. From the time when he was a toddler, when he spoke his first word, when he learned to crawl, when learned to walk over to the time when he was 7. Now, having one's childhood on full display like that would make the manliest of men embarrassed, and I don't care if they eat nails for breakfast.

Needless to say, this got Mirio feeling quite conflicted. Do the years of constantly, and uncontrollably, getting naked in public make a person less shy? Probably. But do they make them immune? No. This was more than he could handle. He turned around, showing her his back and hiding his expression from the view. That's when Nejire really started getting crushed by guilt.

"L-Look, I'm sorry, I'll make amends – somehow. I'm not trying to make excuses, but I really got carried away by the moment and… and I didn't think your dad would just send them without even asking why. I-I'll buy you lunch… and carry your stuff and… and yes! Your guns! Your guns, they're cool too! I don't mind them anymo-"

"Alright, alright." He cut her off.

Turning around again, he saw her on verge of tears, pouting and embarrassed, like a child that knows it's about to get scolded. The strong blush of guilt spreading from ear to ear, she looked like a stressed tomato.

Keeping his hands behind his back, he added: "It's fine. Don't beat yourself over it."

"R-really? Are you serious?" The idea was preposterous to her, and the color slowly returned to her face.

"Yeah, it's not that big of a deal. And besides, I'm flattered that you found me cute… as a kid." The words came out somewhat bitterly, as if he regretted that he couldn't end the sentence sooner.

"Really!? You're the best, I mean it!" She rushed in and gave him a big, tight hug.

"Oh, and by the way" he began while lifting his right hand and showing his phone, "while you were on your apologetic crusade, I went ahead and asked my dad to send me more of them."

"Wha-really? Let me see!" She threw her hands over his shoulders, trying to reach for his phone, but he was one step ahead, and raised his hand out of her reach. All the guilt and shyness in her was gone now.

"Buut, only if – you agree to what I'm about to tell you."

"Oh, so it's a bribe then? I'll agree to anything, now gimme!" And with this he had her right where he wanted her.

"Only if… you agree…" His face was gradually getting closer to hers, until she couldn't see anything but that. Jerking her head back on a reflex didn't help; she didn't notice his left hand on her back, pressing her against him. She could feel her face heating up, but from the looks of it, so was his.

And just when she thought he was about to do it, a grin stretched on his face.

"… to go through them with me!" Nejire surprised herself for being ready even for a kiss. "After all, I can't have you laughing all by yourself." He said, and gave her his phone.

"Ohh, sure." It took her few moments to recollect herself. Now with the phone in her hand she could see the pictures. A lot of new ones were there, he didn't lie. But strangely enough, her right hand remained hanging on his shoulder; too lazy to pull itself back. And for that matter, she didn't feel like making distance, either. "For a moment there, I thought you'd ask me out, or something."

But looking at the phone left her right cheek completely exposed, to which Mirio placed brave and heartfelt kiss. She froze.

"Now, had you only let me finish, you would have heard that too…" she slowly turned her head, to take a better look at him. But once again he was ahead of her; whispering to her ear: "and since you already agreed to it, we'll have to decide which goes first…" The breath of his words sent shivers down her spine.

Now leaning his head back, so they could be face-to-face again, he continued:

"Pictures or…"

"You."

Now hugging her with both his hands, they sealed the deal with the kiss.

A/N: for anyone wondering what happened to Tamaki, they took him to nurse's office later. And to no one's surprise, there was nothing wrong with him.

Anyway, this second story of mine was much more fun to write. Hope y'all didn't cringe too much reading this. Stay safe and stay home! o/
