Chapter Text
When Oikawa woke up in the morning, he was expecting to see his boyfriend Iwazumi lying next to him, probably still asleep. He would've woken him up and said ' rise and shine, Iwa-chan ! It's time to go to school!' He'd be probably hit in the head for that, earning a comment from his grumpy boyfriend before begging to get ready for the day.
Instead, he woke up in a different body, in a different house with a different person in the bed.
Oikawa was utterly confused. Is something like that even possible? What kind of magic was this? He looked at the person next to him, who was still sleeping. It appeared to be a man with very long hair. He has never seen a man with who had such long hair. He thought of waking him up, but how was he going to explain this? Hi, I swapped bodies with your boyfriend (he assumed this body belonged to his boyfriend) my name is Oikawa Tooru ! But it's not like he could act like the man in which body he was in as he didn't know anything about him.
Needles to say, this entire situation was a mess he didn't know how to get out of.
The first logical thing for him to do was to look at a mirror. He should at least know how he looked like. By now, he realized that this person was an adult and had a very well build body. He was a bit jealous, but he'd never admit it to anyone.
He stepped into the bathroom, looking for a mirror and stopped in front of it.
'Why do I have a feeling that this guy is some kind of a clown?'
This man was pretty tall, he had red hair and yellow eyes. But there was something about him that rubbed Oikawa the wrong way. He turned around, wanting to observe the rest of the body more, and then noticed something on his back. There seemed to be a tattoo of some sort, with a spider and number 4 on it.
The first thing he thought that it was maybe because the man just like spiders, but that was highly unlikely. No one would make such a big tattoo because of it. The second thing that came to his mind was that this man was probably a part of some organized crime group, which would explain why he was feeling so uncomfortable.
'This is really going to be tricky', he thought to himself.
"I'm guessing you're not Hisoka ?"
Oikawa flinched at the sound of the voice that came from the door. The man that was next to him in the bed was now awake. And naked. They clearly had something together.
The other thing that really caught Oikawa's attention next to the man's hair, were his eyes. They were pitch black and looked as if he was dead. He was also feeling a bit uneasy with him. Whoever this Hisoka guy was, he was definitely a dangerous person.
Guessing that the unknown man wanted some sort of answer, Oikawa responded to him.
"Nope! I'm Oikawa Tooru !"
'Great. Nailed it Tooru '.
______________________________________
Iwazumi expected to be woken up but his boyfriend who would be screaming at him to get up and get ready for school. It wouldn't be unusual for Oikawa to just decide to crash into Iwazumi's house and sleep there for a few days. His parents already got used to it and he kind of because a part of the family.
But instead of his loud and obnoxious boyfriend, he was greeted by something much different.
Oikawa was sitting on the window of Iwazumi's bedroom. He never did that before.
"Oi, Shittykawa, why are you sitting on the window?"
Oikawa turned his head around but didn't respond right away. Another thing not typical of him. Normally he'd respond immediately to anything that was said to him.
He then smiled. But the smile wasn't Oikawa's. This had to be someone else.
"Good morning. I am guessing that this body belongs to someone named Oikawa?"
______________________________________
Iwazumi was familiar with this whole thing. It happened to him too. There was a myth about how there is a possibility to, on a very rare occasion, swap bodies with someone for a day. People said that this extended over to alternative universes and confirmed them as something that exists. Iwazumi didn't believe in any of that. Well, up until it happened to him and he woke up as a 30-year-old man who was a 'pro hero', who thought English in a hero high school and had his own radio show. That day was the biggest mess in his life and he will never forget it. After that first time, it happened a few more times, but at that point, he managed to somewhat communicate with this man and both of them figured out how to act like each other when it happened. While they weren't able to transfer their talents, making some of those days really hard for volleyball practice, they somehow managed it. But it was a very rare thing. In fact, it happened 3 times in total.
After that experience, Iwazumi was somewhat expecting this to happen to Oikawa too. And now was that time.
"Yes. I'm Iwazumi Hajime, his boyfriend. And you are?"
"Call me Hisoka ", the man said. It wasn't familiar to him, which meant that there was a possibility that he was from an alternative universe. And that meant that Oikawa may get into some trouble if he's in a bad position.
"Tell me Hisoka , when Oikawa wakes up, what will he encounter?" He has to know that Oikawa was going to be okay. If something happened then... He didn't know what would actually happen if someone died while in this body swap, but the possibility of dying was still there.
"He'll wake up next to my boyfriend, of course!" Hisoka seemed pretty chill about all of this. Has this happened to Oikawa before and he just didn't know about it? When he went through this the first time, it was weekend so there wasn't much of a possibility for him to mess something up. Oikawa also didn't know this happened to Iwazumi , which was the main reason why the other to times the day after it he commented on how he wasn't that good the previous day.
"Alright. Is this the first time this happened?"
"Yes, the first time. I'm surprised that I get to swap a body with a teen I must say".
'So he's an adult.' It was a bit of valuable info for him. Now Oikawa had even more things that he could mess up. Imagine if this guy lost his job because of Oikawa. He'd hate him for the rest of his life.
"Okay. One more thing. Is... Is Oikawa going to be okay? There's a good possibility that he'll mess something up, so don't be surprised if something horrible is awaiting you tomorrow.
Hisoka let out a laugh. "Well, I think Illumi doesn't have any assassinations planned for today, so he should be fine. I doubt he'd get into trouble with Illumi around".
".... Assassination!?"
This guy, Illumi , was an assassin!? Then Hisoka must be doing something as bad as that guy!
"Ah yes, Illumi is from a family of assassins. I assist him sometimes. Don't worry though, he should be fine, that's a promise!"
He wasn't sure if he could trust him though.
"How about you tell me something about your friend-"
"Boyfriend"
"Boyfriend Oikawa! That way people won't suspect that it's not him."
That was something he had to do. Oikawa was lucky that he wasn't alone in this. He had luck because that pro hero wasn't living alone and had someone who knew all of this, but the guy didn't have that much luck here. Again, everything turned out fine, but the initial confusion, especially if you've never heard of the body swap, can really break down the person.
Iwazumi had to make sure that doesn't happen here and he was hoping Oikawa will get that.
