"Serena, quickly! We're gonna late!"
"Ok, geez! Don't rush!"

Our story started with a raven-haired boy and a short honey-blonde haired girl.

"Ash, can you just slow down a bit?" The girl asked the boy
"No, I don't want to be late on Friday, so quickly, Serena!" The boy shouted back

They were Ash Ketchum and Serena Yvonne. They were best friends since childhood. It was a summer camp that brought them together

*flashback*
(This was similar to Serena's childhood memory in the anime, except no Pokemon, just think of it)
*end of flashback*

"Wow, that flashback was fast" Serena said
"I know, even it's faster than you, so hurry up" Ash shouted to Serena, immediately made her mad. She then grabbed his hair
"You said what, Ash?" Serena asked while squeezing it
"Ok, ok! Let go of it, I'm sorry! That's my weakness" Ash begged while panicking. Serena let go and both of them continue running to school

Their school was Lumiose High. Unfortunately, the entrance was shut
"Oh no, we're late" - Serena knelt down in desperate
"Hell no! I promise we will get in there!" Ash picked Serena back up then thought about a way to get in. He found a wall edge that was able to grab
"Serena, we're gonna climb!" Ash said determinedly
"What?! That's risky. We can't-" Serena got cut off
"And wait to dead out here? I'm not gonna die like that Harambe meme" Ash quickly climbed on the wall. Soon he was on top, he offered his hand to Serena
"So, you're coming or not?" Ash asked. Serena nodded and grabbed his hand. Ash pulled her up, but he couldn't take it much longer, so both of them collapsed and fell off. Luckily, they managed to got inside

"Uh, Serena, you're on top me" Ash told Serena. Soon she realized she didn't take any damage from the fall, but she fell on top of Ash. She was blushing red
"What's wrong, Serena? You have a fever?" Ash asked. Serena sighed in relief because Ash was oblivious as always
"I'm okay, Ash. Let's head to class!" Serena got off him, then both of them ran to the first class, Math

Time past to lunch time. Serena hanged out with the other girls in class, while Ash just hanged with the boys as usual
"So, Serena, how was sitting on Ash feel?" The long blue-haired girl, Dawn, smirked
"W-what?! No, I'm not" Serena panicked while blushing
"Oh c'mon, We all saw that" The orange-haired girl, Misty, said
"Uh, you see, it was just an a-accident. Yeah!" Serena panicked
"Girl, you really need to confess your feeling to him." May, one of the girl, said
"N-No, h-he just a friend to me. W-we don't have any significant feeling to each other" Serena blushed
"Uh huh..." Iris, also one of Serena's friends, smirked. Little did they know, the boys were also talking about the same topic.

"So Ashy boy, what do you feel when a girl sit on you?" Gary, also Ash's best friend, asked
"Meh, it's normal. It just an accident" Ash answered
"You're so lucky, boy, she would slap your face man" Drew, Lumiose High's hotboy, said
"Even science can't explain it, I don't know why" Clemont, one of the nerds of the school, said
"Look, guys. I only know her as my best friend. End scene. We are not a couple" Ash said

Time past as they were walking home. Ash and Serena walked together, as usual
"So what were you talking about, Serena?" Ash asked
"No, just some... girl stuffs" Serena blushed from what Ash just asked
"You know, some boys are weird. They just call you and I couple. Can you believe that?" Ash asked
"Y-Yeah, couple, who would? We're just friend, right?" Serena panicked while she was blushing much more red
"Uh, Serena, you should consider going to the doctor. Your face is heating"
"Yeah, Ash, I-I will" - Serena panicked - "Hey, there's my house. Bye Ash"
"Bye, Serena" Ash waved goodbye

Serena walked into her house as her mom, the excellent Rhyhorn racer, Grace Yvonne, greeted her
"Hey, how's my little future Rhyhorn racer going?" Her mom asked
"Oh, it's ok, mom" Serena answered but more like a whisper
"Don't be like that, Serena. You have to follow your family business when you're older. All right, get change, 30 minutes for dinner"
"Ok, mom, I'm going now" Serena walked upstairs. Soon she got to her room, she burried her face in a pillow. She never want to be a Rhyhorn racer, as she wasn't sure her strength was suitable for this, instead, she wanted to be a performer. However, she didn't want to talk about that to her mother

The same thing happened to Ash as well
"Oh look who's home, our future businessman" Ash's mother, Delia Ketchum, said
"Mom, look, I don't want to be a businessman" Ash sighed
"Well, you have no choice, young man. You're gonna follow the family business whether you like it or not" - Delia said - "All right, go to your room. Dinner shall be ready soon"
"Fine, whatever, mom." Ash groaned and walked upstairs. Just like Serena, Ash didn't want to follow it. But he couldn't decide what he want to be in the future.

After dinner, both Ash and Serena chatted

Ashy-kun: Hey Sere, what's up?

SerenaHoneyCake: Oh nothing, just don't have what to do

Ashy-kun: Wow, being in a famous family must be cool, huh. No work, no sweat, all we need to care about is media and paparazzi

SerenaHoneyCake: Yeah, but you know, I knd of want to live like you

Ashy-kun: What, I thought you have perfect life

SerenaHoneyCake: It's quite complicated, don't ask. Hey, do you mind switching with me?

Ashy-kun: The heck you just said?

SerenaHoneyCake: You know, I switch my life, you switch yours, for a week, ok?

Ashy-kun: You must be mad, woman

SerenaHoneyCake: Hey you know there's one movie in Disney about switching just with one text message

Ashy-kun: Ikr, so delusional

SerenaHoneyCake: I'm wondering...

Ashy-kun: I don't like the sound of that

SerenaHoneyCake: If I talk about swapping your body with mine, will it happen?

Ashy-kun: Oh it will, woman

SerenaHoneyCake: You said it delusional

Ashy-kun: But everything can happen in this book, Serena, EVERYTHING!

SerenaHoneyCake: Nah, I'll say it

Ashy-kun: You better off, woman

SerenaHoneyCake: Or what?

Ashy-kun: Or I will send hundreds of Trash dove stickers and make you die of irritation

SerenaHoneyCake: Fine, go ahead

*100 Trash dove later*
SerenaHoneyCake: You done?

Ashy-kun: Wait, how could you?

SerenaHoneyCake: I just turned off Notification, how 'bout that?

Ashy-kun: Well, s#!t

SerenaHoneyCake: I want to swap my body with Ash

Ashy-kun: .... Nothing happen

SerenaHoneyCake: Yeah, I guess it really is delusional. Well, good night Ash

Ashy-kun: Good night, Sere

*Ashy-kun logged off*
*SerenaHoneyCake logged off*
Both of them all went to sleep for all that happened. But little did they know, the author is a true savage

Next morning, Ash woke up, and soon he found something strange. His chest was a bit... bigger and he wore pink pajamas, which he hadn't had one before
Serena also woke up at the same time. She realized that something was kind of pointing out her lower zone, and also she wore blue pajamas without a bow on her hair. They both grabbed a mirror to see what happened
"WHAT THE F IS THIS?!" They shouted in unison
