A/N: First One-shot to the list of 100 yoai one shots! It starts with KakaGai, But there will be the other couples I listed later. Promise! I do not own any character. Though I am in the process of gaining Lee.

Rivalry: Kakashi is remembering the time when he first met Gai. Then when he gets to Tsunade's late, she's had it. She makes him go on a mission with Gai. Besides the mission going through well, something else, begins to spark. KakaGai

------------------------------------------------------------------------------------------------------------

Kakashi remembered long ago. After Obito died, his group got a new teammate. Miato Gai. Just a bushy-browed kid he never paid much mind to because he was so annoying.

"Kakashi! Why don't we spar for training today?" The bushy browed kid wearing green said.

"No. I have more important things to do then train with you." A younger Kakashi said while looking at a flyer for a new book called Icha-Icha paradise. Gai frowned and looked disappointed.

"You know, I just want to be a friend and healthy rival to you. Everyone always talks about how good you are. I just want to help you and myself be better." Kakashi watched as Gai turned and tried to walk away.

"Listen, Gai, maybe…if I'm not busy…I'll train with you. Sometimes." Gai turned back around with a smile and leaped and wrapped an arm around Kakashi's neck.

"Great! Together, we'll be some of the strongest ninja this village has ever seen!"

----------------------------------------------------

Kakashi turned over in his bed. He didn't care to remember that. It didn't mean anything except the first time he met Gai. Kakashi picked himself out of bed and grabbed his clothes to go to Tsunade's to get some incredibly strange mission only a jonin can do.

"Kakashi! You're late again, as usual." Tsunade was scolding him for being late. Gai had his hands on his hips watching as he does everyday when Kakashi's late.

"So, what's your lame excuse this time?" Tsunade said while giving him the stink eye.

"Well, my mind got lost in a fog and I'm guessing my body fallowed." Kakashi said still obviously just trying to annoy Tsunade for yelling at him.

"You're an idiot, for that, I'm giving you a mission with Gai." The two looked shocked.

"WHAT?" They yelled out.

"You heard me. You're both going on this mission. End, of, story." They gave each other the same looks Naruto and Sasuke gave each other as 12 year olds. Kakashi rolled his eyes and they listened to the mission objective.

----------------------------------------------------

They shot each other dirty looks while walking down the dirt road out of Konaha.

"I want to run Kakashi."

"Not a chance. We don't have to be there fast, so just enjoy the walk there." Gai disdainfully turned his head. He doesn't like taking his sweet time on a mission.

"You don't have to tell me what I can and can't do."

"No, but when you have more energy in case we have to fight, you'll thank me." Kakashi said while pulling out his book. Gai mumbled curses under his breath.

"Well, then can you at least take off that mask?" Kakashi looked from the book for only a second.

"Fine." He look off the mask to reveal the lighter colored mask. Gai's face got an angry look.

"I meant so I can see your face! I've known you for years and never saw you without it! Just let me see." Gai reached for the mask and Kakashi slapped his hand away.

"No. Bad Gai. Do not touch this mask."

"But-"

"No buts! You know not to touch it so don't!" Gai disdainfully averted his gaze back down to the dirt road. Why are the cool ones always so mean?

---------------------------------------------------------------------

"You know Gai, it wasn't necessary or wise to open the second gate."

"Yeah, Yeah." The mission went well, and Kakashi made Gai walk slow again. Kakashi was bruised up. (Sorry, I'm not good at writing fight scenes). Gai on the other hand had cuts, bruises, and a big black eye.

"I hate you."

"Keep talking Gai. I'm barley listening." Gai shot Kakashi a dirty look.

"It's not fair. Why do you always act like that?" Kakashi looked up from his book.

"Act like what?"

"Like you never care for anyone. Why?"

"I care, I care for my team of genin, where ever Sasuke and Naruto maybe. And I care yo-" Kakashi stopped there and shoved his face back into his book. Gai smiled and blushed a bit.

"You care for me?" Gai said cockily.

"I never said you. I said yo, that is different. I could have meant someone else."

"It isn't youthful to hold in emotions Kakashi."

"Youth is wasted on you."

"Kakashi…" Gai's sentence trailed off. Kakashi's hand shook a bit.

"I don't care what you do to me. Nothing on this Earth, will ever make me say I care for you." Gai moved in front of Kakashi. Kakashi walked right into Gai chest.

"Hey! Move!" Gai shook his head, then grabbed and threw Icha-Icha paradise.

"That was mine! I needed that for reading!" Gai laughed and leaned closer to Kakashi's face…and pulled the mask down Kakashi's face. Kakashi's one uncovered eye grew huge.

"No one sees my face for a reason."

"What reason is that?" Gai smiled and waited for an answer that Kakashi couldn't remember.

"I-I can't remember." Gai reached behind Kakashi's head, and pressed his lips to his.
