I own nothing but the plot*

Chapter 1: The problem

"Why in the fuck did I say I had a girlfriend?" Trunks said to himself as he flew to Tokyo. "I couldn't just say I wasn't interested, but no I had to say that I have a girlfriend." Trunks landed in a park and sat down on a bench.

His eyes looked around the park, and they landed on his childhood friend, Usagi. She had grown up since they last saw each other, but they still kept in contact over the years. 'Usagi! She may be able to help me.' He got up and started to walk towards her.

"-I agree with Mamoru, Usagi you need to study harder." Trunks heard the girl with blue hair say to Usagi.

"Ami, I'll be fine." Usagi protested.

Trunks stopped just before the group watching them interact. "Usako, we care about you and want you to be your best." The man with them said.

"But Mamo.." Usagi said.

Taking a deep breath Trunks stepped forward. "Usagi?"

The group turned to face him, Usagi's eyes got wide and she ran to hug him. Her hug was so strong that it made Trunks stumble back, just a bit. "Trunks!" She said, "What brings you here?"

Trunks hugged her back, "Well, actually Usagi…you." He admitted breaking the hug.

"Me? What why?" She asked.

"Uh, Usagi?" The girl with long black hair asked, "Who is this?"

Usagi blushed, "Right, sorry. Everyone, this is Trunks. He's an old friend of mine we haven't seen each other in years. And Trunks, these are my friends."

"Nice to meet you." Trunks said nervously.

Usagi noticed the tone in his voice, "Are you okay?"

"I need a favor from you, Usagi. It's a bit complicated and weird, but please hear me out." Trunks said trying to not make it sound to bad. "I need you to be my girlfriend." Tunks told her.

Usagi started to laugh, "Good one, Trunks. Now what's the actual favor."

"I'm being serious, Usagi. That's the favor, be my girlfriend just for a week or two." Trunks plead. "Look, there is this girl that wants to be with me, but I don't have any interest in her. And I just said I had a girlfriend and now I need one. Just to get this girl off my back."

"No. No way is she doing that." The man, Mamoru, said.

Trunks looked at him, "And who are you exactly, why do you speak for her?"

"I'm her boyfriend, and I say no." Mamoru told him.

Trunks rolled his eyes, and turned to Usagi, "Usagi, you know me, please. I wouldn't ask if I had anyone else but I don' only other women I know besides you are older and married, or a child."

"That can't be true." Usagi said giggling.

"It is, and I can tell you exactly all the women I know. My mom, Goten and Gohan's Mom Chi-Chi, Videl Gohan's wife, their daughter Pan, who is one. Eighteen who is Krillin's wife, and their daughter Marron who is 5." Trunks grabbed her hands, "Usagi, please. I'll do anything, give you anything to do this for me."

"Anything?" She questioned.

Trunks nodded, "Yes, anything."

"Take me flying." Usagi stated bluntly.

Her friends looked at each other, then at her, "Flying? Like in an airplane, Usagi?" Minako asked.

"No, Trunks knows exactly what I'm talking about." Usagi said starring Trunks.

"A flight. Done." Trunks said, "So anything else? Or do you agree to do this?"

Before Usagi could say anything a little girl with pink hair came up to them, "Hi everyone." She said, When her red eyes landed on Trunks they widened for a brief moment, "Who's this?"

Trunks noticed her eyes looked shocked for a moment. "Name's Trunks, little lady. Who are you?"

"ChibiUsa…Why do you have Usagi's hands like that?"

"Just asking for a favor. So Usagi, if I take you flying will you be my girlfriend?" He asked her again, "Please."

ChibiUsa was in shock, "But she's dating Mamoru."

"One more thing, Trunks, before I give you my answer." Usagi told him. She took a step back causing her hands to leave his, "What were those small orange balls with the stars in them? I saw them once at your house and I have always been curious about them."

Trunks glanced to the side for a moment, "I can tell you, but not right now. As that would mean explaining a lot I don't want to right now."

Usagi turned to her friends, her back to Trunks. "So, what do you think?" She asked them.

"I don't think you should, Usako. I mean that's a horrible thing to ask of you."

"Mamoru, he's a friend, and I know he wouldn't put me in this position unless it was absolutely necessary." Usagi said in Trunks' defence. "I want to help him, and I will no matter what you say."

The others looked at her, "Are you sure about this Usagi?" Makoto asked.

"Yes, absolutely." Usagi said confidently.

Mamoru was getting mad, "If you must do this, set some rules." He demanded. "No kissing, no hugging, and you are to only hold hands for no more than a couple minutes."

Usagi turned back to Trunks, "Yes, Trunks I will be your girlfriend for the next couple weeks."

"Thank you!" Trunks said as he picked her up and spun her around. "I promise I won't do anything to her, and I will keep her safe." He told her friends.

Usagi's stomach growled a little bit, "Sounds like you're hungry. What kind of boyfriend would I be if I didn't treat you to lunch?" He asked with a smile, "All of you."

The group walked to the Crown Cafe, Trunks and Usagi were in front talking and catching up, "Oh I forgot to mention last time we talked, but I'm a big brother now."

"Oh you are! That's amazing." Usagi said smiling.

Trunks pulled out his phone, and pulled up a picture of him and his little sister, "Her name is Bulla."

"She's so cute, Trunks." Usagi said, looking at the picture.

He nodded, "Yeah, and she already has Dad wrapped around her fingers."

"She's Vegeta's little princess?" Usagi asked, laughing.

"In more ways than one." Trunks said with a laugh.

"I feel sorry for any guy she may bring home." Usagi said.

Trunks nodded, "Yeah, with me, Dad, Goku, Gohan, and Goten will be there as well if something ever happens. No one will touch her. And not to mention Lord Beerus as well." Trunks said as they entered the cafe. The group lead Trunks to their normal spot. "Order whatever you wish." He told them.

"Who is Lord Beerus?" Usagi asked as they sat down next to each other.

"He's…uh…family friend…you'll meet him one day." Trunks said as he rubbed the back of his neck, a nervous habit that he always did.

Everyone, minus Usagi, placed simple orders. Usagi ordered a burger, fries, a chocolate milkshake, and a couple other things. Smiling Trunks then placed his order, "I'll take one of everything please." The group's eyes widened.

"That's quite a lot of food, Trunks." Mamoru said his voice was still full of anger.

"I know, I eat a lot." Trunks told him, "Not that you need to know that."

The group sat in silence for a couple minutes when Minako spoke up, "You know Trunks, you have the same name as the heir to the Capsule Corporation."

"I should, since I'm him." Trunks told them, "I thought you knew.

"You're that Trunks?!" Minako screamed.

Trunks gave her a confused look, "Yeah, unless you know some else with my name, because if you do I'd love to talk with them."

Rei sighed, "Forgive her, Trunks. She gets starstruck sometimes."

"No worries, I get it." Trunks told them.

"Can you tell us a bit about yourself Trunks?" Makoto asked trying to see if they can get information on him to make sure that Usagi will be safe.

Their food came out as Trunks started, "Sure what do you want to know?" He started to eat the food he ordered. As did everyone else, they were in awe of how much Trunks was eating and how fast.

Ami the first one to get over the shock, "Well, Trunks what do you do on a normal basis?"

Trunks smiled, "I'm a Martial Artist, I train with my Dad everyday, and I work on inventions and engines for my Mom while learning the business."

"You seem like a very busy person." Mamoru stated, "Do you even have time for a girlfriend?"

Trunks glared at him, "Look, Usagi said she's helping me, she didn't have to. I know you're in a relationship, but it was Usagi's choice." Trunks told him, "And I do have time for a girlfriend."

As the two argued back and forth, ChibiUsa was lost in thought. '...I guess I have to come clean to them, Endeyminon lied to them when the Negamoon attacked because I asked him too…I know how this favor is going to end.'

Usagi stayed quiet as Mamoru and Trunks fought. "Mamoru, Trunks, please stop the fighting. For me?" Usagi said quietly.

"Fine, for you I will." Trunks said instantly. He held out a hand to Mamoru, "Can we be civil for her?"

Mamoru stared at Trunks for a few moments with a glare then took his hand, "Only for her."

There was still tension in the air, Usagi noticed how quiet ChibiUsa was. "ChibiUsa, is everything okay?" She asked.

ChibiUsa waved her hands in front of her, "I'm okay, just thinking about…how strong Trunks looks."

"He does seem strong with all that muscle." Makoto added.

Trunks chuckled a bit, "I am pretty strong." He told them, "But that comes from my training."

The group hears the bell over the door chime, Trunks glanced at the door. He groaned, "That's the girl I told you about. Usagi, it's showtime." Trunks had Usagi move closer to him, and he put an arm around her.

The girl approached, her long black hair flowing behind her. "Trunks, there you are. I've been looking all over for you."

"Mai, like I told you, I have a girlfriend. This is her." Trunks told her firmly.

Mai looked at Usagi and raised an eyebrow, "You expect me to believe you are dating her?"

"Yes." Trunks stated more firmly. He got a Vegeta-eques, glare on his face, "If you doubt this again, I will make you regret it. Or should I make Pilaf my personal punch bag? I'm sure he'd appreciate that."

Usagi glanced at Mai, "I am with Trunks, please can you leave him alone?"

"Alright, but the moment I think you slipped up, he will be mine." Mai said. She turned on her heel and walked out.

Trunks left out a relieved sigh, "Thank you. We may have to keep that up for a bit longer."

"She seems intense." Usagi mentioned.

"You have no idea." Trunks said, "Hey, would you all like to come to a party my Mom is hosting this weekend?"

"At Capsule Corp? Where we can meet Bulma Briefs?" Ami said excitedly.

Chuckling, Trunks nodded, "Yeah, it'll be fun. Besides I know she will be there so I need my girlfriend with me."

Usagi blushed a bit, "A real challenge huh? We really have to step it up there?"

"Yeah, but it'll be easy and a lot of people so it'll be easy to slip away if needed." Trunks told her, "What do you all say?"

They looked at each other and nodded, "Sure, we will go."

Trunks smiled, "Usagi, I'll text you later about the details and I'll come by and get all of you. And we can also discuss the flight you want as well."

The groups spent a bit more time with Trunks, until his mother called him and said it was time for him to come home. "I have to be going, it was nice to meet you all." Trunks turned and walked off.

The Senshi watched as he turned a corner out of sight. ChibiUsa however, looked to the sky and saw a gold streak fly in the direction of West City. The group walked to Rei's place and gathered in her room. "Hopefully, this favor doesn't last too long." Mamoru muttered, "I don't trust him."

"Mamoru, I trust him. He's been my friend for many years." Usagi said as she defended him. "Besides, I know this party that Bulma is throwing is going to amazing."

Minako looked at her friend excitedly, "Amazing how?"

"For starters, there will be a lot of food. Good music, and anything else you can imagine. She spares no expense." Usagi explained, "When I was younger, Trunks invited me to a party. There was so much to do and everyone was so nice…albeit they were a bit odd if I remember correctly…"

"Odd? What do you mean Usagi?" Minako asked.

Usagi leaned back in her chair, "Well if I remember right, there was a green man named Piccolo…He was nice, oh and a pink blob-like person named Buu, he likes candy." Usagi explained.

"W-Was it a costume party?" Ami asked, a bit stunned at her friend's statement.

Usagi shook her head, "No, it wasn't."

Everyone looked at each other, unsure of what might happen.
