"H-How did this happened?"

"It wasn't suppose to happen at all! There must be a mistake!!"

Bulma and Goku were looked down at the literally baby Vegeta, he was no younger than a year. How could this happen you may ask? Well, there was something Bulma wanted to test on Vegeta. It was supposed to increase his power, but it turned him to a baby instead. The blue haired woman never calculated that such a thing would occur. Goku on the other hand was trying to process what in the actual world happened? It was the first time he had seen Vegeta as a kid like that. He bent down and picked Vegeta up, he immediately started to struggle to free himself from Goku's grasp.

"We must tell Y/N!?"

Bulma's face paled as she started to panic at the mention of H/C haired woman. She is his girlfriend or yet what Vegeta likes to call his mate. She was tough, exactly like how Vegeta wanted his mate to be. She came with Vegeta when he and Nappa first landed on Earth. Y/N was way protective over Vegeta even though he was a strong and mature man, she just can't stand anyone or anything harming Vegeta. Bulma was scared that if Y/N knew, she would certainly murder her.

She gulped and glared at Goku, "Are you crazy? I still want my head in its place!" She exclaimed, fear consuming her. Goku looked at her puzzled, "Why? She must know, maybe she can help." Bulma shook her head, "The only thing she will do is kil-" There was a knock.

"Bulma, I came to check on Vegeta." The voice of Y/N rang from the outside the lab.

The inventor trembled when she heard the female Saiyan outside, "Oh no! Quick hide Vegeta!!" She whispered/yelled at Goku, but before he could do anything Y/N came in. Goku immediately hid Vegeta behind his back, keeping a tight grip on him. Both of them turned to Y/N with a panicked look, "Hi Y/N! What a surprising visit!" Bulma said cheerfully yet nervously while Goku just laughed.

Y/N raised an eyebrow suspiciously at them, "Where's Vegeta?" She bluntly aske, well more like demanded. "Oh, he just went outside! He will be back soon I assure you!" She could say that Y/N didn't believe them and that was cleared when Vegeta bite Goku's hand to get free. Goku screamed in pain as Vegeta flew from behind him, making his way to Y/N. 

Vegeta wrapped his arms around Y/N's neck as she held him. She pulled him away and inspected the child, "He looks familiar..." She stared at him for sometime. The same hair, the same frown, even the same vibe and ki. It then clicked, "VEGETA!?" She shouted out of shock. Y/N couldn't wrap her mind around the thought of Vegeta being a child. She immediately glared daggers at both of her friends, "What did you do to my Vegeta?" She asked.

Bulma explained to her what happened and how Vegeta became like this. Y/N was beyond frustrated, "You should better find a way to turn him back!" With that, Y/N stormed out of the lab and back to her home along with baby Vegeta.

💫💫

The next day, Bulma called Y/N and told her that what happened to Vegeta was a temporary side effect of her experiment, it will wear off after at most a week. During this time, Y/N noticed how clingy Vegeta was as a child. He would never leave your lap or go away from Y/N when they go out, but she had to admit that little Vegeta was so adorable. He shows so much affection then his adult self.

Right now, Y/N and Vegeta were just chilling in their peaceful spot. It was an opening in the forest, there was a small lake. Both of them were relaxing, everything was calm. Vegeta was walking around the area, being in Y/N's eye sight. He then returned to Y/N and extended his arm to Y/N, he had a beautiful F/C flower, "For me?" She asked as she pointed at herself. Vegeta nodded, a visible blush on his cheeks.

Y/N giggled and took the flower, "Thank you Vegeta." She then put the flower behind her ear and then pulled Vegeta to hug him, giving him a kiss on his cheeks. He blushed deeply and looked down, "You are so cute Vegeta." He frowned at her state and looked up at her.

"No!"

He said the only word he leaned during his 'second childhood'. Y/N giggled and popped his nose, "You're making me wish for you to remain a baby!" His eyes widened when she spoke up and shook his head, "No no no!!"

"Alright alright, geez! Anyway, let's have a snack, I'm sure you are hungry."

Both of them had eaten and continued to play. But just then, Goku appeared.

He waved at them, "Hey Y/N, Vegeta, how is it going?" Noticing Goku's appearance, Vegeta immediately frowned and clung into Y/N, giving Goku a sharp glare. If only looks could kill... Y/N turned to Goku and nodded in greeting, "How is little Vegeta?" He asked and the H/C haired woman shrugged, "He is fine. The same Vegeta, but in a smaller body."

"I came to see if you're doing good or not."

"Well, I manage."

Aa they spoke, Vegeta was still giving Goku death stares. He was fuming over how Goku was talking with his mate like he wasn't there. Goku noticed something on Y/N's cheek near her lips, "Oi Y/N, you have something on your cheek." He said, pointing at the area on her cheek.

"Oh...here?" She tried to wipe it, but missed. She tried several times, but couldn't wipe it off, "Here let me help." Goku said and went to remove it, but a harsh slap met his hand, "No!" Vegeta yelled. He wiped the small escarp off her cheek with a scowl on his face. He then kissed Y/N's cheek and wrapped his arms around her neck.

Goku and Y/N looked at each other for a while then decided to try something, they were as if reading each other's thoughts. "Say Y/N, I never told you this, but you look beautiful today!" Goku goofily yet slyly smiled and Y/N did the same, "Really? Thank you Goku, that's very nice of you to say." She giggled and Vegeta frowned more, he was getting angry very fast. Goku then leaned forward about to kiss her cheek when suddenly and out of nowhere, a fist connected with his face.

He is so so angry now!

Vegeta glared, a dark look on his face, "Mine! Kakarot no!" He declared, turning toward Y/N and grabbing her face. He planted a kiss on her lips which made Y/N blush a deep shade of red. Goku laughed while holding hid stomach, "Haha! He surely care about you so much Y/N!" He said after both lovers pulled away.

"W-Whatever!"

At the end of the day, Goku went back to his home and Y/N and Vegeta went to their's. Vegeta was already asleep and she was so tired, so she decided to sleep and take a good night rest.

In the middle of the night, Vegeta woke up only to fine himself back to normal. He found himself resting his head on Y/N's chest while his hand held her shirt, "I'm back to normal..." He thought then fixed his sleeping position, pulling Y/N in his arms, "I'm not telling her that I was aware of what I was doing as a baby, she will definitely mock me..." He gave her a kiss on her forehead, drifting to sleep shortly after that.

Bouns Ending:-
"I really like little you more the adult you!" Y/N exclaimed.

Vegeta frowned and looked at her, "And why is that? What's the difference?" He asked, waiting for an answer from her, "You showed me more affection when you were a kid." She replied and he rolled his eyes, "I can grant you this if you just asked."

Y/N sighed, "It won't work...Maybe I should really wish you to be a baby."

"NO!"

The End.
