Reborn sighed as he walked into Vongola Nono's office, he was recently called to do another tutoring job, not that he minds but it takes time out of his schedule to do anything else. Wanting to get this over with he completely ignored the briefing and looked through the file he was given. It was small, in fact it was practically one page as most of it was Iemitsu's blabbling about his "cute lovable Tuna-fishy" and his wife. Of course that just meant it wasn't useful at all and he plans to just burn it after leaving.

"I accept, Nono." Was his response to the request he mostly ignored.

Getting to Namimori was simple, using a Vongola jet made it also instantaneous, however being in Namimori instantly put his instincts on edge. 'Strange I only get this feeling, oh...' As if to confirm his train of thought he almost bumps into his rival.

"What are you doing here Reborn?" Tsuna asked looking at him suspiciously. Reborn doesn't reply looking twice at Tsuna and at the picture in his hands.

"...your father's an idiot." Reborn said as he handed the papers in his hand to Tsuna.

With an eyebrow raised Tsuna reads the document, and predicably burns it with a furious look on his face. "Well my mentally retarded father is going to get a virus or ten on his main computer and a punch in the face when he gets home, anyway." At the end of his statement both guns were out in a flash.

The shootout that insued soon after destroyed the street, several buildings, and knocked out Kyoya who had got in the way. Still glaring heatedly at each other they walked to Tsuna's home while being completely caked in blood and dust. Since there was only one bathroom they could use they grudgingly shared it. This is where Nana found them scowling at each other in the bath.

"Oh Tsu-kun I didn't know you had a friend over."

"He's not my friend!" Tsuna exclaimed angrily and of course Nana declined to hear him.

"Be sure to invite him for dinner soon!" Nana exclaimed before leaving to make said dinner.

"Now I see why she married the idiot." Reborn stated.

"Yeah at least I didn't end up like that." Tsuna agreed with Reborn for once, he may love his mother but sometimes he questions her sanity.

"Well at least this job won't be completely boring." Reborn stated and Tsuna scoffed but nodded.

"Wanna race to give Iemitsu a computer virus?" Tsuna inquires and Reborn smirks in agreement. Minutes later the sound of furious typing was all that was heard as they complied a completely new virus and competed to download it on Iemitsu's computer faster than the other. Both viruses had an interesting effect but both had finished at the same time resulting in the two scowling at each other.

After a few more challenges they proceeded to fight over the bed.

"This is my bed and it has been for years."

"But I'm your tutor and you do as I say."

"No you're-" The argument goes nowhere and eventually they split the bed in half glaring at each other through the blockade of pillows. Of course one of them could've pulled the extra futon from Tsuna's closet or slept in Ie- the guest room which has a bigger bed, but no they had to argue like an old married couple and compromise like one.

AN: Finally I figured out how to end my little teaser here. I haven't decided whether the next chapter should have a flashback or not and leave you all hanging for awhile wondering how they even met.
